The law of specific nerve energies, first proposed by Johannes Peter Müller in 1835, is that the nature of perception is defined by the pathway over which the sensory information is carried. Hence, the origin of the sensation is not important. Therefore the differences in sensory quality, the difference between seeing and hearing, between hearing and touch, and so on - are not caused by differences in the stimuli themselves but by the different nervous structures that these stimuli excite. For example, pressing on the eye elicits sensations of flashes of light because the neurons in the retina send a signal to the occipital lobe. Despite the sensory input's being mechanical, the experience is visual.
Muller's doctrine of specific nerve energies states that the nature of a sensation is determined not by the stimulus itself, but by the specific nerve fibers that are stimulated. In other words, different nerve fibers are responsible for transmitting different types of sensory information to the brain, regardless of the type of stimulus. This theory helped to establish the concept of sensory coding in neuroscience.
corpus colossum is the structure that links the two hemisphere together. It is made by commisural fibres. I'm not sure about the specific name of the nerve that links the two hemisphere together.
Nervous tissue does not have a specific color as it is made up of cells, fibers, and blood vessels. However, nerve tissue can appear white due to the myelin sheath that surrounds certain nerve fibers.
The phrenic nerve arises from the spinal cord at C3, C4, and C5 nerve levels. It originates from the cervical plexus and innervates the diaphragm muscle, playing a crucial role in controlling breathing.
cranial nerve which 2 pairs arise from neuron cell bodies in forebrain 10 pairs arise from the midbrain and hindbrain spinal nerve 31 pairs grouping into 8 cervical 12 thoracic 5 lumber 5 sacral 1 coccygeal A group of nerve cells or neurons is called ganglia in the peripheral nervous system and nuclei in the brain.
The two point discrimination test measures the ability to discern two distinct points touching the skin. It assesses the density of touch receptors in a specific area, commonly used to evaluate sensory nerve function.
