. Which best describes lateral inhibition in sensory processing. Which best describes lateral inhibition in sensory processing. The precision of locating a stimulus is increased by inhibiting.

Most sensory information destined for the neocortex is relayed through the thalamus where considerable transformation occurs 1 2. A Frequency coding principle. When a stimulus is maintained for a long time action potentials from sensory receptors decrease in.

It is also referred to as lateral antagonism and occurs primarily. Which best describes lateral inhibition in sensory processing. When a stimulus is maintained for a long time action potentials from sensory receptors decrease in.

Which is TRUE regarding the ascending pathways in the sensory system A Specific from BIOL 302 at Medgar Evers College CUNY. Lateral inhibition was first proposed as a hypothesis by Ernst Mach a German physicist in the 1860s based on the tendency of continuous visual gradients to be perceived as discontinuous. Which of the following best describes the concept of specificity in sensory nerve fibers that transmit only one modality of sensation.

Presynaptic axoaxonal synapses reduce neurotransmitter release at excitatory synapses. This creates a contrast in stimulation that allows increased sensory perception. A Most sensory systems are organized according to an anatomical scheme in which information from receptor cells is sent directly to cortex via a monosynaptic connection.

In this dissertation we investigate the parallel pathways formed by mitral and tufted cells MCs and TCs of the olfactory system and. The frequency of action potentials along pathways from the site of a stimulus is increased by lateral inhibition. It was a brilliant hypothesis that has since been confirmed by directed testing Figure 312Lateral inhibition seems to be used in many places in the brain Figure 313.

A Lateral inhibition in the retina. Which best describes lateral inhibition in the somatic sensory system. By recording each optic nerve fibers activity researchers in another study assessing retinal information processing they could pinpoint what stimuli made which cell react and thus create a sort of visual map for us.

This prevents the spread of neuronal activity laterally. Presynaptic axo-axonal synapses reduce neurotransmitter release at excitatory synapses. Lateral inhibition and the resultant sharpening of sensation occur within the central nervous system.

Which of the following statements regarding the processing of sensory signals by a pool of neurons is. One means of transformation involves interactions between. Lateral inhibition disables the spreading of action potentials from excited neurons to neighboring neurons in the lateral direction.

Inhibitory neurons decrease action potentials from receptors at the periphery of a stimulated region Which region of the brain contains the primary visual cortex. In neurobiology lateral inhibition is the capacity of an excited neuron to reduce the activity of its neighbors. B Acuity is determined by the density of receptors the size of receptive fields and by.

D Lateral inhibition results in a stronger signal coming from second-order neurons associated with the central point of stimulation. Splitting sensory information into parallel pathways is a common strategy in sensory systems. Those sensory neurons whose receptive fields are stimulated most strongly inhibitvia interneurons that pass laterally within the CNSsensory neurons that serve neighboring receptive fields.

Lateral inhibition is a common theme in sensory physiology. Which best describes lateral inhibition in sensory processing. C Lateral inhibition occurs when communication is inhibited to second-order neurons receiving information from afferents associated with neighboring receptive fields.

The frequency of action potentials along pathways from the site of a stimulus is increased by lateral inhibition. NPB 101 PRACTICE EXAM 1 Select the correct statements regarding sensory processing. Central excitation of a retinal ganglion cell is surrounded by inhibition a classical example of spatial contrast enhancement a fundamental operation in processing spatial patterns in sensory systems.

Lateral inhibition according to the textbook is inhibition that is transmitted across the retina. Which best describes lateral inhibition in the somatic sensory system. Lateral inhibition C Medial inhibition D Feed-forward inhibition.

Consequently there exists an increased contrast in excitation between neighbouring neurones allowing better sensory acuity. Which best describes lateral inhibition in the somatic sensory system. Yet it is not well understood how circuits in these parallel pathways are composed to maintain or even enhance the encoding of specific stimulus features.

Lateral inhibition is the ability of excited neurones to inhibit the activity of neighbouring neurones.
