where is the seat of intelligence located in the brain
Human brain
Brain activity is made possible by the interconnections of neurons that are linked together to reach their targets . A neuron consists of a cell body , axon , and dendrites . Dendrites are often extensive branches that receive information in the form of signals from the axon terminals of other neurons . The signals received may cause the neuron to initiate an action potential ( an electrochemical signal or nerve impulse ) which is sent along its axon to the axon terminal , to connect with the dendrites or with the cell body of another neuron . An action potential is initiated at the initial segment of an axon , which contains a complex of proteins . When an action potential , reaches the axon terminal it triggers the release of a neurotransmitter at a synapse that propagates a signal that acts on the target cell . These chemical neurotransmitters include dopamine , serotonin , GABA , glutamate , and acetylcholine . GABA is the major inhibitory neurotransmitter in the brain , and glutamate is the major excitatory neurotransmitter . Neurons link at synapses to form pathways and elaborate neural networks , and the activity between them is driven by the process of neurotransmission .
