LOBES
1 FRONTAL
1.1 Motor Bx, Expressive Language & Higher-Order Cognitive fxs
1.2 Primary Motor Cortex

Annotations:

  • Part of pyramidal system Controls vol movement Lesions --> contralateral motor weakness, paralysis, &/or apraxia (disruption in the coordination of complex purposeful movement)
1.2.1 "Intentional Movement"
1.3 Premotor Cortex

Annotations:

  • Anterior to primary motor cortex Active during performance of primary motor actions & when observing others perform familiar motor actions
1.4 Broca's Area

Annotations:

  • 1 of Primary language areas  For most, left frontal lobe Damage --> EXPRESSIVE Aphasia (deficits in written & spoken language) speak slowly and with great difficulty, usually only nouns and verbs, poor articulation, have difficulty repeating phrases, have anomia and an awareness of their deficits
1.4.1 "Impoverished Speech"
1.5 Prefrontal Cortex

Annotations:

  • Higher-Order cognitive fxs Damage Dorsolateral Prefrontal Area --> "dysexecutive sydrome" - difficulties px-solving, planning and abstract thinking Damage to Medial Frontal area--> "pseudodepression" - apathy, lack of motivation and spontaneous movement, and reduced verbal output Damage to Orbitofrontal area --> "pseudopsychopathy" - sexual disinhibition, course language, peculiar and facetious sense of humor, inappropriate social bs and lack of concern for others.
1.5.1 "Executive Functions"
1.6 D/Os: ADHD, Schizophrenia, Bipolar & Broca's Aphasia
1.7 "The Executive"
2 PARIETAL
2.1 "The Touch"
2.2 Processes Touch-Pressure, Kinesthesia, Pain & Temperature
2.3 D/Os: Anosognosia, Ideomotor Apraxia, Contralateral Neglect & Gertstmann's Syndrome
2.4 Somatosensory Cortex
2.4.1 "Somatosensory Input"
3 OCCIPITAL
3.1 "The Mind's Eye"
3.2 Visual Processing
3.3 Visual Cortex
3.3.1 "Visual Info"
3.4 D/Os: Cortical Blindness, Loss of Depth Perception, Visual Agnosia & Other Visual Disturbances
4 TEMPORAL
4.1 Auditory Processing & Receptive Language
4.2 Auditory Cortex

Annotations:

  • Mediation of auditory input Damage --> Auditory Agnosia (can't distinguish sounds) Auditory Hallucinations, & other auditory pxs
4.2.1 "Auditory Sensation & Perception"
4.3 Wernicke's Area

Annotations:

  • Usually LTL & involved in comprehension of language DAMAGE --> Wernicke's (RECEPTIVE) Aphasia - trouble understanding language and produce fluent speech that is normal in rate, rhythm, & articulation but makes no sense. 
4.3.1 "Understanding Language"
4.4 "The Auditor"
4.5 D/Os: Auditory Agnosia, Hallucinations, Deafness, Wernicke's Aphasia
5 Damage at Occipital-Parietal-Temporal = Prosopagnosia
