Quotes About Hippocampus

An accident of brain development stacked the deck against children: the mother had three or four years to fuck with your head before your hippocampus began recording lasting memories. You'd been talking to your mom since you were one year old and listening to her for even longer, but you couldn't remember a single word of what you or she had said before your hippocampus kicked into gear. Your

of the bone even making it into the hippocampus.

Human memories were organized in the hippocampus region, but recent research suggested the information was only stored there on a short-term basis. Later, the hippocampus recoded these memories as electrical patterns across billions of synapses and distributed them for long-term storage over the entire cerebral cortex.

La sensación de familiaridad que irradia un verdadero líder resulta de la capacidad que este posee de incorporar en su experiencia personal la experiencia de la especie. Esta incorporación resulta de la identidad de la conciencia del líder con la conciencia del hipercampo.

hippocampus damage on a national scale can be measured by the number of guns owned by a country's citizens. According to The Washington Post, the U.S. has the highest per capita gun ownership in the world—nearly 90 guns for every 100 people—and the highest rate of gun-related murders in the developed world.4 The hippocampus senses danger lurking behind every tree.

One definitely wants to have a functioning hippocampus. It's all about learning and memory, the part blown out of the water by Alzheimer's disease. It's also the part that is most vulnerable to the effects of stress.

While the hippocampus itself doesn't store memories, it serves to triage our experiences based upon their survival significance.

ketogenic diet has also been shown to reduce amyloid in the brain,25 and it increases glutathione, the body's natural brain-protective antioxidant, in the hippocampus.26 What's more, it stimulates the growth of mitochondria and thus increases metabolic efficiency.27

People who are very Tuned In to context tend to have strong connections from the hippocampus to areas in the prefrontal cortex that control executive functions and that hold long-term memories in the neocortex.

New research shows that when we recall an event, the place cells in our hippocampus that store the location of that event fire again, helping us to locate a memory in both space and time. This explains why retracing your steps can help you remember what you were looking for.

stress weakens frontal connections with the hippocampus—essential for incorporating the new information that should prompt shifting to a new strategy—while strengthening frontal connections with more habitual brain circuits.

Moderate, transient stress (i.e., the good, stimulatory stress) promotes hippocampal LTP, while prolonged stress disrupts it and promotes LTD—one reason why cognition tanks at such times. This is the inverted-U concept of stress writ synaptic.4

Remarkably, the size of neurons' dendritic trees in the hippocampus expands and contracts like an accordion throughout a female rat's ovulatory cycle, with the size (and her cognitive skills) peaking when estrogen peaks.fn6 Thus, neurons can form new dendritic branches and spines, increasing the size of their dendritic tree or, in other circumstances, do the opposite; hormones frequently mediate these effects.

Suppose a major traumatic stressor occurs, of a sufficient magnitude to disrupt hippocampal function while enhancing amygdaloid function. At some later point, in a similar setting, you have an anxious, autonomic state, agitated and fearful, and you haven't a clue why—this is because you never consolidated memories of the event via your hippocampus while your amygdala-mediated autonomic pathways sure as hell remember. This is a version of free-floating anxiety.

During sustained stress, the amygdala processes emotional sensory information more rapidly and less accurately, dominates hippocampal function, and disrupts frontocortical function; we're more fearful, our thinking is muddled, and we assess risks poorly and act impulsively out of habit, rather than incorporating new data.

Cualquier distorsión que el cerebro es capaz de imprimir en la lattice y el hipercampo es una manifestación de poder, desde las que activan las imágenes visuales hasta las que modifican el factor de direccionalidad colectivo.

If you have a lesion in the hippocampus in both sides, you have short term memory, but you can convert that short term memory into long term memory.

Loss of the hippocampus in both cerebral hemispheres disrupts the formation of and access to long-term memory of integrated scenes. Unique events are no longer recalled even if objects and events can still be recognized outside a unique context. One is able to recognize a house as a house, but not the particular house where one has lived. The contextual, episodic knowledge acquired by personal, individual experience is no longer accessible. The generic, semantic knowledge is still recoverable.

For a short time, one or two hours, stress does wonderful things for the brain," Sapolsky told the conference. "More oxygen and glucose are delivered to the brain. The hippocampus, which is involved in memory, works better when you are stressed for a little while. Your brain releases more dopamine, which plays a role in the experience of pleasure, early on during stress; it feels wonderful, and your brain works better.

Imaging studies have shown that exercise increases blood volume in a region of the brain called the dentate gyrus. That's a big deal. The dentate gyrus is a vital constituent of the hippocampus, a region deeply involved in memory formation.

Stress hormones seem to have a particular liking for cells in the hippocampus, which is a problem because the hippocampus is deeply involved in many aspects of human learning.

The earliest portions to shrink are generally the frontal lobes, which govern judgment and planning, and the hippocampus, where memory is organized. As a consequence, memory and the ability to gather and weigh multiple ideas—to multitask—peaks in midlife and then gradually declines.

What poets they were, those anatomists, my dear sir, what names they gave to all those parts, the purposes of which they didn't understand at all: the hippocampus . . . Ammon's horn . . . the corpora quadrigemina . . . the calcarine fissure . . .

Each day my buddy the Hippocampus meets me at my front door and takes me out for a walk then rewards me with some new brain cells. -Johnny Wowk AKA Johnny The Walker
