Dendrites are branches of a neuron that receive the electrical frequencies from other cells in the body. Each dendrite consists of up to 200,000 appendages and increased activity in the spines increases their size and conduction which may play a role in memory and learning. The appendages of a dendrite are spread out over a large space for better reception. The dendrites near and in the brain are much finer because they are specialized for the accumulation information they receive. The surface of a dendrite is covered by junctions that are programmed for the reception of information.
The electrical frequencies are transmitted onto the dendrites through synapses between the cells. Recent research has discovered that dendrites can support action potentials and release neurotransmitters rather than the trait being specific to the axons of a cell. Every second, dendrites receive and relay thousands of synaptic inputs from other cells.
The branching of dendrites is changeable in the adult brain. In larger animals, it’s common for dendrites to grow and react according to their activity. Senility is an effect of the shortening and reduction of dendrites in a number of elderly people. In those certain people, dendrites in the brain retract and shrink causing that person to lose memory and certain thought processes. Alcohol has a detrimental effect on dendrite growth; an extreme amount of alcohol consumption can stunt the growth of that person’s dendrites, causing lack of certain memory abilities.
