Associational cortex introduction
- 1. Associational cortex introduction Domina Petric, MD https://www.coursera.org/learn/medical-neuroscience: Leonard E. White, PhD, Duke University
- 2. Cognition The neural processes by which the brain integrates meaningful stimuli and internal motivations (brain and body states) into awareness and appropriate behavior. Stimuli may be external and detected by the special sensory systems or internal and related to brain and body state (sense of self). https://www.coursera.org/learn/medical-neuroscience: Leonard E. White, PhD, Duke University
- 3. Cognition Brain and body states may reflect emotions, mood, motivations, memory, appetitive drives, injuries, disabilities.... Awareness may be objective or highly subjective. Response may result in somatic and visceral motor output. https://www.coursera.org/learn/medical-neuroscience: Leonard E. White, PhD, Duke University
- 4. Cognition Response may result in altered patterns of neural activity that represent explicit knowledge or emotions, with or without overt motor expression. https://www.coursera.org/learn/medical-neuroscience: Leonard E. White, PhD, Duke University

Behavioral functions Behavioral function Neural process Attention Modulatory influences of brainstem reticular formation, hypothalamus and basal forebrain nuclei on thalamic and cortical processes Recognition Coding of feature representations in primary and higher order sensory cortices Integration Association of disparate processing streams in associational cortices Planning Executive associational cortices in prefrontal cortex Selection, execution Implementation of short and long term plans https://www.coursera.org/learn/medical-neuroscience: Leonard E.

White, PhD, Duke University Anterior Association Area Limbic Association Area Posterior Association Area Auditory unimodal association cortex Visual unimodal association cortex Somatosensory unimodal association cortex Premotor cortex Primary motor cortex Primary somatosensory cortex Primary visual cortex Primary auditory cortex
- 7. Associational cortices They bring together integrating information that is being processed through lower to higher order divisions of sensory and motor regions. https://www.coursera.org/learn/medical-neuroscience: Leonard E. White, PhD, Duke University
- 8. Thalamic nuclei First-order thalamic nuclei send inputs into the sensory cortex. Higher-order thalamic nuclei send inputs into the association cortex and also recieve inputs from the cortex. https://www.coursera.org/learn/medical-neuroscience: Leonard E. White, PhD, Duke University
