The following points highlight the four main lobes of cerebral cortex. The lobes are: 1. Frontal Lobe 2. Parietal Lobe 3. Occipital Lobe 4. Temporal Lobe. 1. Frontal Lobe: It has area 4, 6—motor and premotor area, 4S suppressor area, 8-frontal eye field. In prefrontal lobe, areas 9-12 are present. Areas 44, 45 are called Broca's area of speech and [...]

In this article we will discuss about:- 1. Meaning of Receptors 2. Classification of Receptors 3. Properties. Meaning of Receptors: Certain specialized structures are present at the interface of stimulus and afferent nerve fibers. These specialized structures convert any type of energy into electrical energy or action potential in afferent fiber. This action is known as transduction. Hence receptors act [...]
