All living cells have the ability to receive and process signals that originate outside their membranes, which they do by means of proteins called receptors, often located at the cell's surface imbedded in the plasma membrane. When such signals interact with a receptor, they effectively direct the cell to do something, such as dividing, dying, or allowing substances to be created, or to enter or exit the cell. A cell's ability to respond to a chemical message depends o… WebTop-down modulation Vertical modulation ASJC Scopus subject areas Ecology, Evolution, Behavior and Systematics Neuroscience (all) Psychology (all) Neuropsychology and Physiological Psychology Fingerprint Dive into the research topics of 'What catatonia can tell us about "top-down modulation": A neuropsychiatric hypothesis'.
