- nonM-nonP type (K-type) retinal ganglion cells typically have: large receptive fields and motion sensitivity small receptive fields and color-opponency small receptive fields and motion sensitivity small receptive field without color-opponencyThe discharge rate of an off-center ganglion cell: is not an absolute measure of light intensity does not depend on the background level of illumination O is highest when receptive field is in complete darkness O is the same for center-only and center-plus-surround illumination Which of the following terms are most suitably matched? Pitch, waveform Loudness, amplitude Frequency, pressure Tonotopy, phaseRetinal ganglion cells fire at a variety of rates depending on characteristics of the visual stimulus. Select one: True False
- As you move from V1 to V5 and higher visual centers, receptive fields of individual neurons as indicated by "preferred stimuli" get: More simple More complicated More grandmother-like More surround inhibition If you saw a red afterimage of flag stripes after staring a green-striped flag for a long-time, it is because color opponent cells were: Fatigued fo green, and so the red opponent dominates Fatigued for red, and so the green opponent dominates Fatigued for yellow, and so the blue opponent dominates Fatigued for blue, so the yellow opponent dominatesFrom a biological perspective, how do our senses monitor our body's position and movement? Discuss factors which may influence our vestibular senses. Include a relevant example. Please include references.True or False: In visual receptive fields, light falling in the center always has the opposite effect on activity of the cell than light falling in the surround.
- The correct pathway of activation (by sending neuronal signals) in the retina is bipolar cell - retinal ganglion cell - photoreceptor photoreceptor - retinal ganglion cell - bipolar cell retinal ganglion cell - bipolar cell - photoreceptor photoreceptor - bipolar cell - retinal ganglion cell O bipolar cell - photoreceptor - amacrine cellTrue or false: Only some, not all, LGN neurons project axons to primary visual cortex.The best characterization of receptive fields in retinal ganglion cells that respond best to light-dark contrast is that for a cell that responds to light it has no response to light in its center on field for a cell that responds to light it has a strong response to light in the surround field for a cell that responds to light it has a strong response to light in its center on field for a cell that responds to light it has a weak response to light in its center on field
- A scientist has dissected out a small section of the retina and is able to directly record the action potential firing rate in a single ganglion cell. Assume there is a on-center off-surround bipolar cell connected to an on-center off-surround ganglion cell. When applying ‘Stimulus 1’ the scientist records a moderate action potential rate. When applying ‘Stimulus 2’ the rate of action potentials increases substantially. In the context of this experiment no illumination is an option as a 'Stimulus'. ‘Stimulus 2’ would result in what response in the bipolar cell (the one connected to the ganglion cell the scientist is measuring)? A. A large depolarization of the bipolar cell membrane B. The bipolar cell membrane would remain at the resting membrane potential C. A large hyperpolarization of the bipolar cell membrane D. A small hyperpolarization of the bipolar cell membrane E. A small depolarization of the bipolar cell membraneDraw a simple (typical of somatic senses) and a complex (typical of special senses) sensory neuron (receptor). Where applicable, label the cell body, the axon, the nerve endings, myelin, and the axon terminal.Put the following steps in order for transduction for vision. Question options: PDE breaks down cyclic GMP Photon is absorbed by discs the photoreceptor hyperpolarizes Sodium channels are inactivated and the dark current stops Opsin is activated Phosphodiesterase (PDE) is activated Transducin is activated
