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.
The same neurons that help bats navigate through space may also help them navigate collective social environments, finds a new study published today in the journal Nature.
Most of us who've reached middle age have noticed a slowing in memory and cognition, but scientists don't have a clear picture of the molecular changes that take place in the brain to cause it.
As per a research study in mice from the National Eye Institute (NEI) and the University of Freiberg, Germany, the Noelin family belonging to secreted proteins bind to the exterior part of AMPA glutamate receptors and stabilize them on the neuronal cellular membrane.
Teleost fish encompass a diverse group, among which seahorses display a unique morphology. The characteristic spines and brood pouch seen in seahorses feature distinctive epithelial cells-;called flame cone cells-;covered by a mucous cap.
A brood pouch in male fish and bony plates gives seahorses their distinctive shape.
The human brain uses spatial mapping and memory to steer from point A to point B during daily navigation. Making a navigational error that necessitates a course correction is also common.
Cognitive deficits accompany mood disorders and other psychiatric conditions, often with debilitating effects.
Researchers from the Center for Cognition and Sociality (CCS) within the Institute for Basic Science (IBS) recently announced the discovery of neurons that allow us to recognize others. The research team discovered that the neurons that deal with the information associated with different individuals are located in the CA1 region of the hippocampus.
Neurons in a key area of the brain have different functions based on their exact genetic identity, and understanding this diversity could lead to better understanding of the brain's computational flexibility and memory capacity, potentially informing disease treatment options, Cornell researchers report in a new study.
Epilepsy affects approximately 1-in-26 people and the most common form, known as temporal lobe epilepsy (TLE), often cannot be adequately treated with anti-seizure medications.
People with dementia have protein build-up in astrocytes that may trigger abnormal antiviral activity and memory loss, according to a preclinical study by a team of Weill Cornell Medicine investigators.
Physical activity is often quoted as a method of increasing mental and physical health. Scientists at the Beckman Institute for Advanced Science and Technology have proved that it might also enhance brain health more directly.
MIT neuroscientists have found a way to reverse neurodegeneration and other symptoms of Alzheimer's disease by interfering with an enzyme that is typically overactive in the brains of Alzheimer's patients.
The accumulation of amyloid beta proteins, which encourage synaptic malfunction, causes cognitive decline in Alzheimer’s disease (AD), according to scientific evidence.
Of all the known genetic risk factors for late-onset Alzheimer's disease, the strongest is a gene for the protein called ApoE4.
A new research paper was published on the cover of Aging entitled, "Immune-mediated platelet depletion augments Alzheimer's disease neuropathological hallmarks in APP-PS1 mice."
Here is an important reason to stay in touch with friends and family: social isolation causes memory and learning deficits and other behavioral changes.
By showing Welles's movie "Touch of Evil" to mice, Chinmay Purandare, PhD, and Prof. Mayank Mehta of UCLA have uncovered surprising and important new insights about how neurons form memories. The discovery points to new ways to diagnose Alzheimer's and other learning and memory impairments, while also improving artificial intelligence.
Researchers from Tohoku University have now shown that the consolidation and extinction of contextual fear conditioning alter the microglial genes connected to the synapse—structures that permit neurons to communicate with one another.
The Tob gene is well known for its connection to cancer. Scientists have discovered that this gene also has a significant role in lowering depression, fear, and anxiety in a multidisciplinary study that blends molecular biology with neuroscience.
