Hippocampus News and Research

RSS

The hippocampus is a part of the forebrain, located in the medial temporal lobe. It belongs to the limbic system and plays major roles in short term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain.

Unraveling the Genetic Blueprint of the Deep Brain

Researchers have discovered 254 genetic variations that influence important “deep brain” structures, such as those that govern memory, motor skills, addictive behaviors, and more, in one of the biggest-ever investigations of DNA and brain volume.

Research Reveals How the Brain Encodes Time and Experiences at the Neuronal Level

A landmark study led by UCLA Health has begun to unravel one of the fundamental mysteries in neuroscience – how the human brain encodes and makes sense of the flow of time and experiences.

How Classic Psychedelics Impact Brain Cell Dynamics and Anxiety

A classic psychedelic, similar to LSD, psilocybin and mescalin, was found to activate a cell type in the brain that silences other neighboring neurons, a result that provides insight into how such drugs reduce anxiety, according to a new study.

Insights into Hmmr's Role in Cognitive Decline and Lifespan

The authors investigate the physiological functions of Terc-53 by creating transgenic mice that overexpress this noncoding RNA. They observe that Terc-53 overexpression affects normal aging in mammals, contributing to cognitive decline and shortened lifespan.

Electrical Recordings Illuminate Neural Basis of Inferential Reasoning

It takes brains to infer how any two things in the world relate to each other, whether it's the way bad weather links to commuting delays or how environmental conditions lead to the evolution of species.

New Insights into Memory Formation and Modification

The ability to turn experiences into memories allows us to learn from the past and use what we learned as a model to respond appropriately to new situations. For this reason, as the world around us changes, this memory model cannot simply be a fixed archive of the good old days.

Spontaneous Brain Activity Drives Early Neural Circuit Formation

In humans, the process of learning is driven by different groups of cells in the brain firing together. For instance, when the neurons associated with the process of recognizing a dog begin to fire in a coordinated manner in response to the cells that encode the features of a dog -; four legs, fur, a tail, etc. -; a young child will eventually be able to identify dogs going forward. But brain wiring begins before humans are born, before they have experiences or senses like sight to guide this cellular circuitry. How does that happen?

Brain's Co-Rippling Activity Sheds Light on Consciousness

For many years, researchers have been concentrating on how the brain organizes information into hierarchical structures, with distinct regions of the brain designated for distinct functions.

Mice Studies Shed Light on Serotonin and Memory

Memory regulation in humans and animal models is regulated by the serotonin 2C receptor in the brain, according to research from Baylor College of Medicine, the University of Cambridge in the United Kingdom, and affiliated institutions.

Small Molecule Restores TERT Levels to Combat Aging-Related Decline

Researchers at The University of Texas MD Anderson Cancer Center have demonstrated that therapeutically restoring 'youthful' levels of a specific subunit of the telomerase enzyme can significantly reduce the signs and symptoms of aging in preclinical models.

AI Deciphers the Complex Wiring of the Human Brain

Though it may not seem like much, one cubic mm of brain tissue exists. That small square, however, holds 230 mm of blood vessels, 150 million synapses, and 57,000 cells, totaling 1,400 terabytes of data. That is why researchers from Google and Harvard have just achieved something truly amazing.

The Role of Associative Memory in Spatial Navigation

Human lives revolve around spatial navigation and spatial memory. Without these skills, it would be extremely difficult to remember the past and to navigate the environment. But understanding the neural underpinnings of spatial memory is still quite incomplete.
