Sentences with phrase «medial entorhinal»

Flavio Donato's work has revealed that, during development, stellate cells in the medial entorhinal cortex are the source of an activity - dependent instructive signal necessary for the maturation of those neurons that give us a sense of where we are.

To optically manipulate specific connections to these engram cells, a blue light - sensitive protein oChIEF was expressed in an upstream brain region, i.e., medial entorhinal cortical inputs (red) to the DG.

Border cells are relatively sparse, making up less than 10 % of the local cell population, but can be found in all layers of the medial entorhinal cortex as well as the adjacent parasubiculum, often intermingled with head - direction cells and grid cells.

To search for such cells, the Mosers and their team delved into the medial entorhinal cortex (MEC), a slim arc of deep brain tissue where they had discovered the grid cells in 2005.

To determine how information is represented in this area, we measured spatial modulation of neural activity in layers of medial entorhinal cortex projecting to the hippocampus.

Precise positional modulation was not observed more ventromedially in the entorhinal cortex or upstream in the postrhinal cortex, suggesting that sensory input is transformed into durable allocentric spatial representations internally in the dorsocaudal medial entorhinal cortex.

A rat's position in space can be represented in the medial entorhinal cortex in addition to the neighboring hippocampus, the area previously thought to be the only locus of spatial information.

Not exact matches

«Our results suggest that aerobic exercise may have a positive effect on the medial temporal lobe memory system (which includes the entorhinal cortex) in healthy young adults.

The medial temporal structures, including the hippocampus and the entorhinal cortex, are critical for the ability to transform daily experience into lasting memories.

Our results show that spatial learning in humans can be enhanced by electrical stimulation of the entorhinal region, a specific site within the medial temporal lobe and the chief gateway into the hippocampus.

Neuropsychological data suggest that the left medial temporal lobe is better suited to verbal learning32 and that the right medial temporal lobe is better suited to nonverbal (e.g., visuospatial) learning.33 Although two subjects in our study had stimulation in the left entorhinal area, our study is too small to support conclusions about laterality effects.

Decades of research and clinical observations have established that declarative memory, the ability to remember recently experienced facts and events, depends on the hippocampus and associated structures in the medial temporal lobe, including the entorhinal, perirhinal, and parahippocampal cortexes.1

Her work has demonstrated that, for some types of memory, the entorhinal and perirhinal cortical regions in the ventral medial temporal lobe play a more important role than does the hippocampus.

The medial septal area projects to a large number of brain regions that show theta modulation, including all parts of the hippocampus as well as the entorhinal cortex, perirhinal cortex, retrosplenial cortex, medial mamillary and supramamillary nuclei of the hypothalamus, anterior nuclei of the thalamus, amygdala, inferior colliculus, and several brainstem nuclei (Buzsáki, 2002).
