Video Lectures

Displaying all 23 video lectures.

Lecture 1 Play Video	Introduction: The Visual System This lecture covers the layout and organization of the course, as well as separate introductions to the visual system and the auditory system.
Lecture 2 Play Video	Basic layout of the visual system and the retina This video covers the basic layout and components of the visual system, including retinal ganglion cells, photoreceptors, biopolar, horizontal and amacrine cells.
Lecture 3 Play Video	The laternal geniculate nucleus and the visual cortex This lecture covers the lateral geniculate nucleus and the anatomy, receptive field organization, cytoarchitecture of the V1, extrastriate cortex, V2, V4, MT, MST and inferotemporal cortex areas.
Lecture 4 Play Video	The ON and OFF channels This lecture describes the ON and OFF retinal ganglion cells, retinal connections and the effect of a glutamate analog called 2-amino-4-phosphonobutyrate (APB) on vision.
Lecture 5 Play Video	The Midget and Parasol systems This lecture describes the Midget and Parasol channels. It includes a discussion of how lesions of the LGN affect contrast sensitivity, brightness perception, pattern and texture perception, depth, motion and flicker detection.
Lecture 6 Play Video	Adaptation and Color This lecture describes the features of and major theories behind color vision. It covers how color is processed in the retina, LGN and cortex as well as color blindness and adaptation.
Lecture 7 Play Video	Depth Perception This lecture covers depth perception, including mechanisms used to analyze depth such as the effects of lesions in V4 or MT, stereo-blindness, parallax, shading and perspective. It also describes how depth is processed by cortical structures.
Lecture 8 Play Video	Form Perception This lecture describes form perception, including Gestalt, three major theories and properties of spatial frequency analysis. Also covered are cortical areas important to intermediate vision, subjective contours and facial recognition.
Lecture 9 Play Video	Illusions and visual prosthesis This lecture demonstrates various illusions and analyzes theories for their explanation. Additionally, the instructor discusses the requirements of visual prostheses and the current state of research on them.
Lecture 10 Play Video	The neural control of visually guided eye movements 1 The video describes visually guided eye movements, including saccades and smooth pursuit movements. Also covered are the extraocular muscles, the cranial nerves and the parts of the brain required for these movements.
Lecture 11 Play Video	The neural control of visually guided eye movements 2 This video covers saccadic eye movements and the role of the superior colliculus and cortical regions on those movements. The video includes a discussion of the effect of lesions and certain pharmacological agents on saccadic eye movements.
Lecture 12 Play Video	Motion perception and pursuit eye movements This video covers motion perception,including the role of motion parallax. The instructor also discusses structure from motion, apparent motion, brightness masking and optokinetic nystagmus.
Lecture 13 Play Video	Review: The visual and oculomotor systems This video reviews important topics from the visual and oculomotor systems lectures.
Lecture 14 Play Video	Sound: External, Middle and Inner ears Instructor: Chris Brown This video describes the physical characteristics of sound and the roles of the three components of the auditory periphery.
Lecture 15 Play Video	Hair Cells Instructor: Chris Brown This video describes the anatomy of the cochlea, inner and outer hair cells as well as OHC electromotility and otoacoustic emissions.
Lecture 16 Play Video	Auditory Nerve;Ppsychophysics of frequency resolution Instructor: Chris Brown This video covers the auditory nerves and frequency resolution, including tuning and tonotopy, frequency discrimination and phase locking.
Lecture 17 Play Video	Cochlear nucleus: Tonotopy, Unit types and Cell types Instructor: Chris Brown This video covers the anatomy and physiology of the auditory central nervous system and the cochlear nucleus and introduces auditory implants.
Lecture 18 Play Video	Hearing loss; Demo by Sheila Xu, Cochlear implant user Instructor: Chris Brown, Sheila Xu This video covers the features and causes of hearing loss as well as cochlear implants and features a discussion with a cochlear implant user.
Lecture 19 Play Video	Descending systems and reflexes Instructor: Chris Brown This video covers the auditory brainstem and reflex pathway components, including the olivocochlear neurons and middle ear muscles.
Lecture 20 Play Video	Sound Localization 1: Psychophysics and neural circuits Instructor: Chris Brown This video covers sound localization using binaural cues, including the psychophysics and neural circuits.
Lecture 21 Play Video	Sound Localization 2: Superior olivary complex and IC Instructor: Chris Brown This video continues to discuss sound localization, including neural processing in the lateral superior olive and inferior colliculus. It also covers the auditory pathways in Barn Owls.
Lecture 22 Play Video	Auditory Cortex 1: Physiology and sound localization Instructor: Chris Brown This video introduces the auditory cortex, including its physiology and role in sound localization. Also discussed is the pitch area.
Lecture 23 Play Video	Auditory Cortex 2: Language; bats and echolocation Instructor: Chris Brown This video discusses echolocation by bats and the cortical processing of language.
