Answer :
Neurons come in three different orders. Signals are sent from the peripheral to the spinal cord by first-order neurons, and they are sent from the spinal cord to the thalamus by second-order neurons.
In the centre of your brain is a structure called the thalamus that resembles an egg. It serves as a relay station for all incoming hearing, taste, sight, and touch (but not smell) sensory information from your body to your brain. All information must first pass through your thalamus, which functions as a relay or train station, before being routed or directed to the cerebral cortex, the outermost layer of your brain, for additional processing and interpretation. transmitting sensory data. obtaining data from all of your senses in the form of nerve signals. just smell enters your brain. A thalamic nucleus is responsible for processing and transmitting information from each sensory function to the corresponding region of your cerebral cortex. relaying information about movement (motor). Your thalamus is the hub of all motor pathways, just like it is for sensory information.
