Sentences with phrase «cells in the hippocampus which»

The prize is for discovering «the brain's navigation system»: place cells, cells in the hippocampus which are active whenever a rat is in a particular place, and grid cells, cells in the entorhinal cortex which are active when the animal is at multiple locations in a grid pattern.

Chen and his team began by studying how reactive glial cells respond to a specific protein, NeuroD1, which is known to be important in the formation of nerve cells in the hippocampus area of adult brains.

The research team selectively overexpressed a transcription factor, Klf9, only in older neurons in mice, which eliminated more than one - fifth of their dendritic spines, increased the number of new neurons that integrated into the hippocampus circuitry by two-fold, and activated neural stem cells.

«We also noticed an accumulation of debris of interneurons — the cells that serve as a connection between sensory and motor pathways for reflexes — in the hippocampus, which is responsible for memory storage.»

John O'Keefe, along with John Dostrovsky, discovered in 1971 that the hippocampus contains special nerve cells that are involved in determining an animal's specific location, which they called place cells.

The scientists implanted neural stem cells into the hippocampus, which is a brain region involved in making new memories and connecting them to emotions.

The CBM now forms the core of the new Kavli Institute at Trondheim, which was inaugurated in August 2007 and where research continues on grid cells, as well as areas such as understanding the role of the hippocampus in shaping memory.

Dr. O'Keefe's research identified neurons in the hippocampus, called place cells, which respond selectively to an animal's location.

As its name implies, FTD is a fatal disease that destroys cells, or neurons, that comprise the frontal and temporal lobes of the brain — as opposed to Alzheimer's which mainly affects brain's memory centers in the hippocampus.

Studies in rats have shown that physical exercise boosts BDNF (brain - derived neurotrophic factor — a molecule that promotes the growth and survival of brain cells) levels in the hippocampus, which is a brain structure crucial for learning and memory formation.

Develops new nerve cells from the stem cells (blank cells) in the hippocampus, which is the part of the brain related to memory and learning.

Cortisol has been shown to damage and kill cells in the hippocampus, which is the area of the brain responsible for episodic memory.

Cortisol overproduction has been shown to shrink nerve cells in the hippocampus and stop the formation of new hippocampus neurons, which can cause aging and memory problems.

Stress - activated cortisol bombards the memory center, killing nerve cells in the hippocampus, and attacks the immune system, which often causes depression and anxiety.
