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.
A hospital nurse for 33 years, Nanette Miller would call her husband Frank at the end of each shift to let him know she was coming home.
The hippocampus is a region within the brain that contains many neurons that help us to navigate in space. This leads to the nickname of this area: the GPS of the brain.
Studies on cellular dynamics are vital to interpret the development of cells and the progression of various diseases.
Among the many things rodents have taught neuroscientists is that in a region called the hippocampus, the brain creates a new map for every unique spatial context - for instance, a different room or maze.
Primary cilia are structures that act like antennas for cells to identify signals and occur less in mice affected by Fragile X syndrome since birth.
The ability of the human brain to process and store information is determined to a large extent by the connectivity between nerve cells. Chemical synapses are very important in this context as they constitute the interface for the transmission of information between individual nerve cells.
A new radiotracer, 18F-SynVesT-2, can directly assess synaptic density changes in the brain, providing an objective and quantitative measure of disease progression after stroke.
To make new memories, our brain cells first must find one another. Small protrusions that bud out from the ends of neurons' long, branching tentacles dock neurons together so they can talk.
For the first time, a team of researchers from Lobachevsky University has theoretically validated the existence of concept cells.
Brain function depends on inhibitory cells that balance or 'brake' excitation. These neurons allow the brain to process information and also prevent runaway seizures.
Degenerative diseases such as Alzheimer's often involve complex interactions between multiple proteins and other biomolecules.
Imagine you are meeting a friend for dinner at a new restaurant. You may try dishes you haven't had before, and your surroundings will be completely new to you. However, your brain knows that you have had similar experiences -- perusing a menu, ordering appetizers, and splurging on dessert are all things that you have probably done when dining out.
