The hippocampus is also one of the brain regions most affected by Alzheimer's disease, a.. Although there is near universal agreement among scientists that the hippocampus is important for memory, the exact processes by which the hippocampus supports memory are subject to much debate. Some studies suggest that the hippocampus binds items and contexts into unified experiences and stores them. Other studies suggest that the hippocampus is preferentially involved in conscious recollection, or the experience of mental time travel during recall. Still other studies suggest that the hippocampus is able to support rapid learning by reducing interference among similar memories (for example, where a person parked his or her car today versus yesterday). Some theories of hippocampal function treat the hippocampus as an index (much like an index at the end of a book) that binds together elements of an experience but does not store the experience itself. The latter is assumed to be stored in a distributed fashion throughout the brain, while the hippocampus is assumed to possess an index of that distributed code.

The hippocampus is the key to your long-term memory. In an attempt to cure him, daredevil surgeon Dr. William Skoville removed H.M.'s hippocampus The two most-influential theories for hippocampal function are related to space and memory. The spatial hypothesis was supported by the seminal discovery in 1971 of cells in the hippocampus that fired bursts of action potentials when a rat traversed specific locations in space, or “place fields.” That suggested that the hippocampus was a sort of device used by the brain for mapping layouts of the environment. Data supporting that idea came from later virtual navigation studies in humans, which suggested a strong association between the hippocampus and spatial navigation. The memory hypothesis originated in 1957 and was supported by studies and observations in which hippocampal removal resulted in a loss of the ability to form new memories, particularly fact- and event-related (declarative) memories. The hippocampus is a part of the brain that plays a key role in memory and how However, the healthy function of the hippocampus can be affected by Alzheimer's.. Figure 2. Summary of the delayed effects of stress on hippocampal neurons and astrocytes, reflecting primarily genomically-mediated effects of GCs. Over the course of minutes to hours after a stressor exposure, GCs increase AMPAR and NMDAR insertion into the post-synaptic membrane but reduce plasma membrane GluTs. Glucose transport and metabolism are downregulated in astrocytes and neurons, production and metabolism of lactate is lowered, and expression of prometabolic genes is reduced. The overall effect, under normal physiological circumstances, is to downregulate both neuronal firing and metabolism, acting to reverse the short-term impact of stress and promote optimal memory for stress-related events with minimal or no cellular damage. The increase in glutamate receptors may potentiate the response to subsequent or prolonged stress, potentially including excitotoxic damage. Preparing for exams?

Daniel B. Block, MD, is an award-winning, board-certified psychiatrist who operates a private practice in Pennsylvania.

One of these symptoms is a reduction in the size of the hippocampus.

The limbic system is situated on the edge of the cortex, and it includes the hypothalamus and the amygdala.There is disagreement about whether long-term memories eventually become independent of the hippocampus, with the cortex being sufficiently able to support recall. That is known as the standard model of systems consolidation. The major competing theory, multiple trace theory, suggests that the hippocampus continues to be needed for long-term recall of episodic (context-rich) memories but not for semantic or gist memories. Finally, hippocampal structure, function, and connectivity are not uniform along its longitudinal axis. The anterior hippocampus is preferentially connected to the amygdala and orbitofrontal cortex and is thought to be involved principally in the regulation of emotion and stress. The posterior hippocampus is preferentially connected to the retrosplenial and posterior parietal cortices and is thought to be involved principally in cognitive and spatial processing.Wingenfeld K, Wolf OT.

The hippocampus is a brain area involved in memory that animal studies have shown to be sensitive to the effects of stress. Meanwhile, studies in adults with post-traumatic stress syndrome (PTSD) related to either early childhood abuse or adult traumas like combat have found smaller hippocampal volume. Two recent meta-analyses of the literature on PTSD and hippocampal volume (Kitayama and colleagues 2005, which I co-authored, and one by Michael Smith, also in 2005) found smaller volume for both the left and the right hippocampi in both men and women with chronic PTSD. But does stress cause the hippocampi to shrink, or do smaller hippocampi simply make people more vulnerable to stress? A number of factors have been implicated as possible mechanisms for stress-related reductions in hippocampal volume, including increases in cortisol, increased levels of glutamate (a neurotransmitter) and decreased levels of brain-derived neurotrophic factor (BDNF). But so far no one has been able to determine definitively whether stress shrinks the hippocampus or simply preys more heavily on people that already have small hippocampi. Asking the question sooner One way to answer this question is to study children who have recently undergone stress and see if the stress seems to affect their hippocampi. The few studies published to date, however, have not even found smaller hippocampal volume in children with PTSD. A study published last March in Pediatrics, however, examined the hippocampi of 15 children (six boys and nine girls) age 8 to 14 with PTSD related to various kinds of physical, emotional and sexual abuse and neglect and got results a bit more meaningful. The study was conducted by a team of University of New Orleans and Stanford Unversity researchers led by Stanford psychiatrist Allan Reiss. Diagnosis of PTSD was established with the Clinician Administered PTSD Scale for Children and Adolescents (CAPS-CA), a common diagnostic tool. The researchers then took two important measurements: They measured salivary cortisol, elevations of which are associated with PTSD, and took magnetic resonance imaging (MRI) scans of the children's brains. They did this testing twice -- once soon after diagnosis, and once about 12 to 18 months later. They found a significant negative correlation between cortisol levels and other PTSD symptom severity at baseline and changes in right hippocampal volume over time. In other words, patients with the highest baseline cortisol and most severe PTSD symptoms had the greatest decreases in hippocampal volume over time. Catching the change This finding is significant because it addresses the puzzle about why studies had shown that adults with histories of early childhood abuse had smaller hippocampal volume, whereat the few studies performed in children (including an earlier study by Reiss and his collaborators) did not show any difference from controls. Studies in animals have shown that early stress may not necessarily cause an immediate effect on the hippocampus, but rather a delayed response leading to changes in hippocampal structure during development. Meanwhile, a study of twins led by Mark Gilbertson suggests a genetic contribution to smaller hippocampal volume in patients with PTSD; in twin pairs in which one twin had PTSD and the other did not, both would have small but similarly small hippocampi, suggesting that the smaller hippocampal volume was a risk factor for PTSD rather than a result of stress. Take all this together -- the Reiss paper, the animal literature showing hippocampal damage as a result of stress, and the twin study showing small hippocampi as risk factor for PTSD rather than result -- and it seems likely that there is a combined genetic and environmental contribution to smaller hippocampal volume in PTSD. A small hippocampus makes you more vulnerable to stress's ill effects, including damage to the hippocampus. Particularly intriguing is the correlation the Reiss study found between high cortisol and progressive reductions in hippocampal volume over time. As the authors note, one possible explanation for this finding is that high cortisol has a toxic effect on hippocampal neurons. Although there is debate on this topic, several studies in animals have reported this effect. Another possibility is that elevated cortisol is a marker of severity of PTSD status rather than a cause, and individuals with the most severe PTSD are also those with the highest baseline cortisol and the greatest propensity to develop hippocampal volume reductions over time. It isn't clear how these two possibilities could be disentangled in research studies involving clinical populations. A letter to the editor of Pediatrics, the journal in which Reiss's piece appeared, called "Stressing about posttraumatic stress disorder," various methodological issues were raised, such as accuracy of measurement of the hippocampus, small sample size, use of multiple statistical tests and a prior longitudinal study in children with PTSD that did not show changes in hippocampal volume over time. However, as the authors pointed out in their reply, MRI measurement of hippocampal volume can be highly accurate, and small sample sizes are not a reason to discount the results of an otherwise solid study. In fact, if statistically significant results can be found with a smaller sample size, that may in fact increase the strength of the findings. Overall, this study provides important information regarding the effects of stress on the hippocampus, strengthens evidence that small hippocampal size may be both risk factor and result of PTSD -- and points to the value of more future studies that follow patients with PTSD longitudinally.

Figure 1. Schematic summary of the rapid effects of stress hormones on metabolism and glutamate transmission in hippocampal neurons and astrocytes. NE increases glycogen breakdown in astrocytes, with subsequent lactate release. NE also upregulates GluT translocation in the post-synaptic neuron, increasing glucose transport, energy production, and firing during memory processing: increased glucose metabolic demand is likely driven primarily by restoration of the neuronal membrane potential after glutamate-induced depolarization. AR activation also promotes phosphorylation of CREB which increases LTP and memory formation. Rapid effects of GCs include upregulation of presynaptic glutamate synthesis and release.

Uncontrollable stress has been recognized to influence the hippocampus at various levels of analysis. Behaviorally, human and animal studies have found that stress generally impairs various hippocampal-dependent memory tasks. Neurally, animal studies have revealed that stress alters ensuing synaptic plasticity and firing properties of hippocampal neurons. Structurally, human and animal studies have shown that stress changes neuronal morphology, suppresses neuronal proliferation, and reduces hippocampal volume. Since the inception of stress research nearly 80 years ago, much focus has been on the varying levels of hypothalamic-pituitary-adrenal (HPA) axis neuroendocrine hormones, namely glucocorticoids, as mediators of the myriad stress effects on the hippocampus and as contributing factors to stress-associated psychopathologies such as post-traumatic stress disorder (PTSD). However, reports of glucocorticoid-produced alterations in hippocampal functioning vary widely across studies. This review provides a brief history of stress research, examines how the glucocorticoid hypothesis emerged and guides contemporary stress research, and considers alternative approaches to understanding the mechanisms underlying stress effects on hippocampal functioning.
