Jane is in the lab analyzing receptive fields of two skin areas. She found one receptive field with a diameter of 2 cm. The other receptive field is much smaller, measuring 0.8 cm. She thinks that larger receptive field will give precise sensory information. Explain to Jane about receptive fields and their relationship with precision in the processing of sensory information.

Respuesta :

An area of the skin with a smaller receptive field suggests that there are a large of sensory receptors & therefore the sensation is much more precise compared to the area with fewer sensory receptors. In the areas, with larger receptive fields, the smaller sensory neurons may have extensive branches to occupy a wider area.

What do skin receptive fields do?

Pressure, vibration, stretch, motion, edges, points, and other types of touch are all possible. Skin receptors enable the perception of these many qualities, and when this data is merged into the central nervous system, we can discern the position, strength, duration, movement, shape, and texture of the item engaging with the skin. A portion of the skin known as the receptive field of the receptor is where each mechanoreceptor responds to a touch signal. The mechanoreceptor will become active once it is hit by the receptive field. In addition to varying between various mechanoreceptor types, receptive field widths also range between various body parts.

What connection exists between receptive fields and the accuracy with which sensory information is processed?

In the sensory periphery, a region known as the receptive field is where inputs can affect the electrical activity of sensory cells. The sensory receptors that feed sensory neurons are included in the receptive field, which also contains particular receptors on neurons as well as groups of receptors that can synaptically activate neurons. All over the body, including on the surface, in tissues like muscles, joints, and the eyes, as well as in internal organs, are receptive fields. The idea of the receptive field is essential to understanding sensory neurobiology since it describes where a sensory stimulus must be presented in order for a sensory cell to respond.
