Ipsilateral (from Latin ipse ‘same’): on the same side as another structure. For example, the left arm is ipsilateral to the left leg.
Is smell a contralateral?
Compared with those of the other sensory systems, the neural systems for processing chemical stimuli are remarkably different. For example, both taste and smell have ipsilateral ascending projections, whereas those of the other sensory systems are either contralateral or bilateral.
Why our brain is contralateral?
The contralateral control of the brain is to provide an alternative remedy to the problems of the nervous system. The effects of the upper motor neuron lesions can be minimized with the help of physiotherapy or the regular practice of Akhand Yoga.
What is the ipsilateral side?

How sensitive is the human nose?
A human nose has around 400 scent receptors. When the smell of coffee wafts through a room, for example, specific receptors in the nose detect molecular components of the odour, eliciting a series of neural responses that draw one’s attention to the coffee pot.
What side of brain is smell?
In the current study, cells in the right habenula were largely responsible for receiving odor information, while the left-sided neurons processed visual information. Very few neurons responded to both types of stimuli.
How does olfaction occur?
Olfaction first occurs in the sensory cilia of olfactory neurons, and the generated olfactory signals are transmitted to the olfactory cortex and to other area of the brain through synaptic connections of olfactory neurons with downstream neurons, such as mitral or tufted cells, in the main olfactory bulb.

Is your brain contralateral?
The hemispheres of the brain control the contralateral sides of the body. So the left side of the brain controls the right side of the body and the right side of the brain controls the left side of the body. A stroke that causes damage to the left side of the brain can cause paralysis on the right side of the body.
