Sentences with phrase «place cells in the hippocampi»

Close to the postrhinal - entorhinal border, entorhinal neurons had stable and discrete multipeaked place fields, predicting the rat's location as accurately as place cells in the hippocampus.

Place cells in the hippocampus provide a neuronal code for specific locations in space.

«Because the structure we detected was similar in all three experimental conditions, we think that we are picking up the fundamental organization of place cells in the hippocampus,» said Itskov.

In addition, the Honeycomb Maze enables researchers to study the correlation of spatial navigation performance with the activity of place cells in the hippocampus where there is a map of an animal's location in space.

Not exact matches

When both mice and people navigate, specialised «place» cells in the brain's hippocampus fire.

The sex - specific differences — the smaller hippocampus, the presence of fewer nerve cells, the existence of immune system macrophages in places they shouldn't be — were also found in adulthood.

The neurons in the hippocampus that store spatial memories (such as the location where you parked your car) are called place cells.

In the lab, they adapted the standard experimental technique for studying place cells: implanting electrodes directly into a rat's hippocampus and recording from them as the animal runs freely in a large box (see «A sense of place»In the lab, they adapted the standard experimental technique for studying place cells: implanting electrodes directly into a rat's hippocampus and recording from them as the animal runs freely in a large box (see «A sense of place»in a large box (see «A sense of place»).

For their analyses, the scientists specifically colored the places of origin of axons of so - called pyramidal cells in the hippocampus.

To find out if these chemical changes do indeed take place, the researchers first identified a group of engram cells in the hippocampus that, when activated using optogenetic tools, were able to express a memory.

John O'Keefe discovered that certain cells in a region of the brain called the hippocampus preferentially fired, or were activated, when an animal was in a particular environmental location — the first description of «place cells».

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.

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.

In 1978, working with Lynn Nadel, O'Keefe expanded this notion and suggested that in addition to the place cells, the hippocampus might also contain information about direction and distancIn 1978, working with Lynn Nadel, O'Keefe expanded this notion and suggested that in addition to the place cells, the hippocampus might also contain information about direction and distancin addition to the place cells, the hippocampus might also contain information about direction and distance.

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

The idea that the activity of a place cell is predictive and can be modified by learning and the behavior of other animals may make it easier to conceptualize an all - encompassing framework that ties together the hippocampus» role in spatial navigation with its well - established role in learning and memory formation.
