Exam 3 review Vision • Stimulus for vision – Spectrum of visible light – Eye as light collector (chambered vs. compound eyes) – Transduction by photoreceptors in retina • The retina – Rods and cones • Variations in location and density; function – Horizontal, bipolar, amacrine, and ganglion cells – Fovea – Blind spot Vision • Coding the stimulus – Retinal ganglion cell receptive fields • On/Off arrangement • Correlation detectors for motion – LGN cell receptive fields • Ocular dominance columns – Area V1 • Simple, complex and hypercomplex cells – Agnosia (what) and ataxia (where) Hearing • Stimulus – Sound pressure waves • Amplitude (loudness), frequency (pitch), complexity (timbre) – Transduction • Stages of processing in ear • Basilar membrane and hair cells • Pathways – Auditory cochlear nerve – Cochlear nucleus – Medial geniculate nucleus – Primary auditory cortex (A1) – Dorsal and ventral streams Hearing • Coding – Place theory of pitch perception – Loudness and cellular firing rate – Tonotopic map in A1 – Wernicke’s area – Localizing sound Motor control * Corticospinal tracts — Lateral and medial tracts Somatosensation • Receptors – Hairy skin, glabrous skin – Tendons, muscles, joints – Fast vs. slow adapting – Types of receptors and specificity of stimulation • Types of touch – Active and passive – Nociception – Proprioception – Haptics Somatosensation • Pathways – Dorsal root ganglia in spine – Spinothalamic tracts • Dorsal and ventral divisions – Medial lemniscus – Ventrolateral nucleus – Primary somatosensory cortex (post-central gyrus in parietal lobe)
