The process by which a cell in a multicellular organism interprets its surroundings.

The process by which a neuronal cell in a multicellular organism interprets its surroundings.

The processes pertaining to the functions of the nervous and muscular systems of an organism.

The process by which a neuronal cell in a multicellular organism interprets signals produced by potential target cells, with which it may form synapses.

detection of stimulus during sensory perception

The series of events during sensory perception in which a sensory stimulus is received and converted into a molecular signal.

detection of chemical stimulus during sensory perception

sensory transduction of chemical stimulus during sensory perception

The series of events in which a sensory chemical stimulus is received and converted into a molecular signal.

detection of light stimulus during visual perception

visual perception, sensory transduction of light stimulus

The series of events during visual perception in which a sensory light stimulus is received and converted into a molecular signal.

The series of events required for an organism to receive a gustatory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Gustation involves the direct detection of chemical composition, usually through contact with chemoreceptor cells.

establishment of neuroblast cell polarity

The specification and formation of the apicobasal polarity of a neuroblast cell, a progenitor of the central nervous system.

The junction between a nerve fiber of one neuron and another neuron or muscle fiber or glial cell; the site of interneuronal communication. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
