Introduction This chapter focuses on the Diagnostic Interview. A lot of this is basic “good interviewing practice” even if someone is not from another culture. These are the major points to keep in mind from this chapter from Cross Cultural Neuropsychological Assessment, Theory and Practice, Chapters 8-9 by Victor Nell Major Points Think of the … Read more

Cortices: Parietal and Temporal Lobes

TEMPORAL LOBE Hippocampus Some controversy as to whether or not it encodes (material-specific) or represents only a cognitive/ spatial map (memory) Rat studies suggests spatial map (i.e., lesion here, no longer able to find platform on Morris milk maze based on spatial cues from env; also stimulation and single cell recordings support this) Monkey studies … Read more

CNS Cellular Organization and Communication

GENERAL INFO Billions of cells in CNS (10-50 times more glial cells than neurons) 12-15 billion neurons in cerebral cortex 1 billion in spinal cord Neurons operate w/in interconnected networks number of connections between neurons ranges from 1,000 to 100,000 (average 10,000) Share many characteristics with other cells of bodies, but also a number of … Read more

Childhood Disorders

CHILDHOOD DISORDERS CEREBRAL PALSY Nonscientific term describing permanent, nonprogressive neurologic motor system impairment resulting from CNS injuries of the immature brain (occur pre- or peri-natally, infancy, or early childhood); .2% incidence Can be associated with prematurity (especially as smaller premature infants continue to survive) and low birth weight; however, specific causes have not yet been … Read more

Chemical Senses

GUSTATION Stimuli Only 4 qualities of taste: bitterness, sourness, sweetness, and saltiness Flavor (not taste) is composite of olfaction and gustation (aside: most vertebrates taste all four; exception: cats, who don’t detect sweetness) Anatomy of Taste Buds and Gustatory Cells Tongue, palate, pharynx, and larynx contain approximately 10,000 taste buds Most receptors are around papillae, … Read more

Cerebral Hemispheres and Vascular Supply

Review of Main Functional Areas of Cerebral Cortex Sensory areas for face and hand are on the lateral convexities while the leg areas are in the interhemispheric fissure Broca’s area in inferior frontal gyrus, just anterior to the articulatory areas of the primary motor cortex Wernicke’s area lies in the superior temporal gyrus, adjacent to … Read more

Cerebellum

Anatomical and Clinical Review The Cerebellum The cerebellum is the largest structure in the posterior fossa (see figures 15.1, 15.2, & 15.3). It is attached to the dorsal aspect of the pons and rostral medulla by three white matter peduncles and forms the roof of the fourth ventricle. It consists of: Vermis – the midline … Read more
