"Cognitive adventures of single neurons in the human medial temporal lobe"



The human medial temporal lobe contains neurons that respond to the semantic contents of a presented stimulus. These "concept cells" may respond to very different pictures of a given person and even to their written or spoken name. Their response latency is far longer than necessary for object recognition, and they are found in brain regions that are crucial for declarative memory formation. It has thus been hypothesized that they may represent the semantic "building blocks" of episodic memories.

In this talk I will present data from single unit recordings in the hippocampus, entorhinal cortex, parahippocampal cortex, and amygdala during paradigms involving object recognition, conscious perception, working memory, and encoding and consolidation of episodic memories in order to characterize the role of concept cells in these cognitive functions.
