Document Summary
If not, will modify signals: diencephalon, thalamus: receives sensory input as it travels from spinal cord. Neurons eye: located in peripheral nerves, sensory in nature transmit signals to/from spinal cord, cell body lies in middle and to one side of body, multipolar: contain many branching dendrites, common in cns. Glial cells: glial means glue holds things together, support cells of the brain maintain internal environment of cns, control passage of substances between blood and brain"s, also regulate nutrients and interstitial environment interstitial space, astrocyte, microglia, oligodendrocytes: produce myelin. Neural coding: action potential is language, if holding something light, weight is coded in action potential, chemical synapse: how nerve cells communicate using neurotransmitters to cause a single action potential on a presynaptic cell that will not produce. Epsps generated at different synapses on same postsynaptic neuron at same time: temporal summation: additive effect produced by.
