The occipital lobe has two areas viz. On the ventral side there is a longitudinal fissure called rhinal fissure which separates the hippocampal lobe or pyriform lobe from anterior lobe in each cerebral hemisphere. Insula or Island of Reil is a small lobe of cerebrum, covered over by parietal frontal, and temporal lobes. It co-ordinates the action of different regions of cerebral hemispheres. The outer layer of cerebral hemispheres is called cerebral cortex or neopallium. It is formed of grey matter and contains millions of neurons. Grey matter also forms islands on the white matter. These are called cerebral nuclei. The cerebral cortex is highly convulated in order to increase its surface area.
The ridges of these convultions are called gyri and depressions between them as sulci. The cavities within the cerebral hemispheres are called lateral ventricles First and second ventricles which open to third ventricle cavity of diencephalon by a foramen of Monro Fig. iii Cerebrum responds to pain, touch, cold etc. The centres of reception of these are located in the sensory areas called soma esthetic area present in the parietal lobe. It is the last part of the forebrain and is almost covered dorsally by cerebral hemispheres. On its dorsal surface it bears a pineal stalk with a rounded pineal body at its top. The dorsal vascular wall forms anterior choroid plexus. Its cavity is called diocoel or third ventricle. On the ventral side hypothalamus forms the floor of the diocoel.
It consists of number of scattered masses of the grey matter in the white matter. The pituitary hangs below the hypothalamus by a stalk called infundibulum. Below pituitary is mammillary body. Two optic nerves cross each other to form optic chiasma in front of the pituitary Fig. Diencephalon regulates manifestations of emotions and recognizes sensations like heat, cold and pain. Hypothalamus contains nerve centres for temperature regulations, hunger, thirst and emotions. It also produces various neurohormones that control the secretions of anterior pituitary. Hormones of posterior pituitary are produced in hypothalamus and later transported to pituitary. Hypothalamus contains higher centres of autonomic nervous system and controls carbohydrate, fat metabolism, blood pressure and water balance.
The Pineal body or epiphysis is an endocrine gland producing the hormone melatonin which controls pigmentation in certain animals. Recently it has been claimed to function as a Biological clock regulating day and night periodicity. The mid brain connects cerebral hemispheres with cerebellum. It consists of optic lobes and crura cerebri. There are four, solid optic lobes, which arise from the dorsolateral side of the mid brain. They are collectively called as corpora quadrigemina. In case of frog there are two hollow optic lobes which are together known as corpora bigemina. The anterior pair of optic lobes are called Superior colliculi and the posterior optic lobes are called Inferior colliculi both are formed of grey matter.
The former acts as the centre for visual reflex and the latter acts as centre for auditory reflex. On the ventral side of mid brain in its floor there are two large longitudinal bands of nerve fibres called crura cerebri sing, crus cerebrum which connect the medulla oblongata with the cerebral hemisphere. The cavity of the mid brain is in the form of a narrow canal called iter which connects third ventricle with the fourth ventricle. The optic lobes are the centres of visual and auditory reflexes. The crura cerebri controls the activities of the eye muscles. Cerebellum is the second largest part of the brain. Like cerebral hemispheres its upper surface is formed of grey matter and forms cerebellar cortex and the deeper central part is medulla formed of white matter.
Cerebellum maintains equilibrium, and controls posture. It modulates and moderates voluntary movements initiated in cerebrum. It makes the movement of the body smooth, steady and coordinated. The brain stem consists of pons varoli in front of cerebellum and medulla oblongata behind, the latter continues behind as spinal cord. Pons varoli is composed of thick bundles of transverse nerve fibres which connect two sides of the cerebellum. It coordinates muscle movements on the two sides of the body. Medulla oblongata is the posterior most part of the brain. Its cavity is called fourth ventricle or metacoel. The roof of the medulla is thin and vascular forming posterior choroid plexus, the latter secretes cerebrospinal fluid.
Medulla oblongata controls all the involuntary actions of the body. It has cardiac centre to regulate heart beat , respiratory centre to control rate and depth of breathing , gastric centre controls flow of gastric juices , reflex centres controls act of swallowing, vomiting, salivation, choking etc. It acts as a pathway for conducting impulses from spinal nerves to spinal cord and then to brain.
