7 The Cerebral Hemispheres and lobes 14 Central sulcus Lateral sulcus! The FRONTAL LOBE and PARIETAL LOBE are separated by the CENTRAL SULCUS.! The TEMPORAL LOBE is between the parietal and frontal lobe, separated by the LATERAL SULCUS.! The OCCIPITAL LOBE does not have a real border; it s just a region.! These are the anatomical areas, but the functional areas are more important.

11 ! The CORPUS CALLOSUM is the area that connects the right and left halves of the brain. CORPUS CALLOSUM 16
12 Sheep brain Corpus callosum 17
13 This is the area that is responsible for the right half of the brain communicating with the left half of the brain. If the corpus callosum was cut, there would be no communication between the right and left halves of the brain. Autism is a neurological disease that includes problems with communication between the right and left cerebral hemispheres.

28 Diencephalon
29 Diencephalon 1. Thalamus - process sensory information - major relay station for sensory impulse to cerebrum 2. Hypothalamus - make hormones which maintain the homeostasis of the body 3. Subthalamus 4. Epithalamus; Habenular nucleus, Pineal gland
30 Sits on the top of the brain stem Enclosed by the cerebral hemisphere Exposed only to the lower part

33 Thalamus 27 Hypothalamus Pituitary gland 28 Thalamus Hypothalamus Pituitary gland
34 Thalamus Gateway to cerebral cortex Most sensory stimuli project to the thalamus, which in turn project to the cerebrum Thalamus also influences moods and activities associated with strong emotion. Sensory integration Transfer impulses to the correct part of the cortex for localization and interpretation
35 HYPOTHALAMUS Under the thalamus Important autonomic nervous system center - helps regulates body temperature - controls water balance - regulates metabolism An important part of the limbic system (emotions) The pituitary gland is attached to the hypothalamus Endocrine system; hormone secretion
36 The hypothalamus synthesizes and secretes hormones, and these in turn stimulates or inhibits the secretion of pituitary hormones By secretion of hormones, the hypothalamus controls blood pressure, body temperature, hunger, thirst, fatigue, sleep, autonomic nervous reflexes, and circadian cycles.
37 Subthalamus Localizes inferior part of thalamus, adjacent to hypothalamus at anterior and medial parts red nucleus, substantia nigra connects to the corpus striatum and involves in muscular regulation
38 EPITHALAMUS Forms the roof of the third ventricle Consists of pineal body and Habenacular nucleus House the pineal body (pineal gland); an endocrine gland Includes choroid plexus - forms cerebrospinal fluid
39
40 PINEAL BODY (PINEAL GLAND) Consists of pinealocyte and glial cell The PINEAL BODY secretes melatonin. How much it secretes depends on the sensory information it receives from the eyes about how many hours of daylight are present. The amount of melatonin secreted and circulating in the blood then determines the circadian rhythm, or the 24- hour biological clock (cycles influenced by light). Therefore, the pineal body detects the number of hours of light and dark, and sets the body s 24-hour clock.
41 Endocrine organ for the regulation of the activities of parathyroid gland, adrenal gland, gonad, islet of LAngerhans

50 CORTEX AND ASSOCIATION AREAS! Each area of the brain has a region where the sensory information comes in, and another area where the information is understood.! The area where the information comes in is a cortex, and the area where it is understood is the association area.! Therefore, there will be a visual cortex and association area, an auditory cortex and association area, and a somatic (sense of touch) cortex and association area. There is also a motor cortex and association area.

52
53 Pre-Central Gyrus! Within the primary motor area of the brain, there is a structure called the pre-central gyrus which contains a precise map of the different body parts.! This map is called a motor homunculus (Latin: little man)! All the neurons that innervate the lips would have their cell bodies in one particular region in this area. All the neurons that innervate the hands have their cell bodies in this area. All those that innervate the back have their cell bodies here.! However, we don t have as many neurons innervating the back as we do for the lips and hands.! The homunculus is drawn to represent how many neuron cell bodies we have that innervate each region of our body.
54 ! Not all body parts are equally represented by cell density in the motor area in proportion to their size in the body.! Lips, parts of the face and hands are drawn large because there are many cells in the motor area that innervate those regions of the body.! The face region of the homunculus is large so we can have many facial expressions. The hands and tongue are large, indicating that we have many fine motor skills in those areas as well.! There is also a somatosensory homunculus.
