How The Structure Of The Nervous System Is Adapted To Its Functions? Nerve cells are also called neurones. They are adapted to carry electrical impulses from one place to another: they have a long fibre (axon) which is insulated by a fatty sheath. they have tiny branches (dendrons) which branch further as dendrites at each
How Did Hebb Define The Assembly? How did Hebb define the cell assembly? Neurons simultaneously activated by an external stimulus that are reciprocally interconnected. What is cell assembly in psychology? a group of neurons that are repeatedly active at the same time and develop as a single functional unit, which may become active when any
What Will Happen If Synapse Is Absent In Between Two Nerve Cells? The formation of synaptic connections between a presynaptic neuron and its target is often critical to the survival of the presynaptic neuron. In many cases if a synapse is not formed, or if an incorrect synapse is made, then the presynaptic neuron will
What Two Things Do Synapses Make It Possible For Neurons? Synapses can be thought of as converting an electrical signal (the action potential) into a chemical signal in the form of neurotransmitter release, and then, upon binding of the transmitter to the postsynaptic receptor, switching the signal back again into an electrical form, as charged
What Are Neural Connections? Via their synaptic connections, brain cells form the neural circuits that somehow support our sensory, motor, and cognitive skills and that ultimately regulate all of our behavior. Neurons do not begin life in a mature state. They take time to develop. Neurons begin to form very early in fetal development. What
What Do Ganglion Cells Respond To? Different types of ganglion cells respond differentially to different types of stimuli, such as onset of light, onset of darkness, motion, direction of motion, color, contrast, and others. This information is encoded in patterns of firing, i.e., depolarization and action potential generation, in the ganglion cells. What do ganglion
