The Prefrontal Cortex: Anatomy, Physiology, and Neuropsychology of the Frontal Lobe, 3rd ed. Schematic of successively higher-order processing of sensory input information and the reverse in the motor hierarchy leading to output responses that interact with the environment. The premotor cortex is rostral to the motor cortex-BrodmannвЂ™s areas 6 and 8. The posterior multimodal association cortex is highly connected to the anterior association areas which in turn are responsible for conceptual cognitive functions and planning motor actions.ДЄfter planning motor actions in the anterior association area, the actual processing of the motor response output is the reverse of processing in the sensory (input) system. Sensory information is processed and sent from receptors along parallel pathways through primary sensory cortex and unimodal association cortex to the posterior multimodal association cortex of each hemisphere-the posterior parietal and temporal cortices. The general principle to be learned here is that as one gets further away from the primary sensory areas the associative functions become more general.

Three unimodal association areas are located adjacent to their respective primary sensory cortical areas as shown in the figure. Important in memory, planning, and higher-order concept formation.

Links information from other association areas. Links information from primary and unimodal sensory areas Located at the junction of occipital, temporal and parietal lobes. Located in the anterior-ventral portion of the temporal lobe, the parahippocampal gyrus.

Three multimodal association areas will be discussed in conjunction with three unimodal association areas and three primary sensory areas. Locations of primary, unimodal, and multimodal (Anterior, Limbic, Posterior) areas.

We were here together chapter 9
