Document Summary
Association areas: composed of neurons that help provide sense and meaning to information registered in the cortex. Cerebral cortex can adapt to changes in sensory input-plasticity. The brain is plastic: functions that were assigned to certain areas of the brain may be capable of being reassigned to other areas of the brain to accommodate changing input from the environment. This suggest that sensory inputs compete for representation in each cortical area. Physical exercise can increase the number of synapses and even promote the development of new neurons. The nervous system is first major bodily system to take form in an embryo-this begins during third week of fertilization. Neural tube begins to develop and you being to form cerebral hemispheres. The hindbrain forms the cerebellum and medulla and the midbrain forms the tectum. Ontogeny of the brain: how it develops within an individual. Within 15 week semester the basic structures of the brain are in place and rapidly developing.
