Describe how it is possible for us to differentiate between stimuli of different modalities in the same body part (i. e. fingertip). consider this at the level of 1) the sensory receptors and 2) the neurons onto which they synapse in the ascending sensory systems.

The stimulus modality is one in which the body response to the stimulus and respond in each way accordingly. Two different stimulus can be used at two different time to sense different operation

Explanation:

There are five different types of sensory modalities and they are the visual auditory gustatory olfactory and the receptors. They function to identify the taste, smell, heat, light and sound. When a specific function is done the following sensory receptors are activated and they respond to the stimulus.

The sensory receptors at the finger tip are stimulated when we touch a hot or a cold object this is one type of function. On the other hand the synapses which occurs at the brain are due to the modulus of the brain activities like vision and responding to the activities.
