Opening Notes: * Interest and research in the brain is at an all-time pace The cure for some common diseases such as Alzheimer’s‚ Parkinson’s and Multiple Sclerosis has accelerated the efforts of many scientists * Many of the names for the parts of the brain have come from Latin and Greek words * The easiest way to learn about the brain is to look at it as three divisions; the hindbrain‚ the midbrain and the forebrain * Modern imaging has allowed us to study the brain and locate

The case study presents Jessie as a healthy woman with no history of medical issues. However on her 50th birthday‚ Jessie begins to express unusual behaviours. Jessie hit the left side of the garage with her car‚ and failed to blow out the left side of the candles on her birthday cake. After each incident‚ Jessie offers up a plausible reason for the unusual behaviour. Jessie is found lying on the bathroom floor unaware of her surroundings and incontinent‚ leading her to consult a neurologists. Neurologists

List some common neurotransmitters and describe their effect on behavior. There are 2 neurons afferent neurons these carry messages to the central nervous system. Efferent neurons carry messages from the central nervous system. Neurons communicate through voltage changes. This can sometimes lead to quick action reaction

Chapter 2 Brain and Behavior The cerebral cortex outer layer of the cerebrum has the two largest hemispheres that covers the upper part of the brain which are divided into smaller portion called lobes. Corticalization is an increase in size of the wrinkling of the cortex and without this we would not be any smarter than any other animal. Cerebral hemispheres are divided into right and left halves of the cortex connected by thick band axon fibers called corpus. Hemispheric specialization‚ testing

Einstein’s high-performance neurons. In addition‚ Einstein’s brain fell in the range of normal for all measurements‚ except for the portion known as the inferior parietal lobes‚ located in the middle of the brain. Einstein’s parietal lobes were bigger and better connected than the norm. Subsequent experiments have shown the parietal lobes are involved in mathematics‚ as well as music and processing of visual images‚ strongly suggesting a biological link between the shape of Einstein’s brain and his

damage to their right inferior parietal lobe‚ the subjects were submitted to two houses that were exactly identical houses where one was on fire on the left hand side. The subjects all said they could not find any major difference between the houses but most said they would much rather live in the house that was not on fire. This leads us to believe that the subjects were not conscious of the left side of their vision due to their damaged right inferior parietal lobe‚ which leads us to believe that

have the several parts that are the same and perform the same function. For instance the medulla oblongata is the lowest portion of the brain (stem) and controls automatic functions. All three of these vertebrates have two hemispheres and different lobes. Each vertebrate also has a spinal cord that descends from the brain that carries nerve impulses to and from the body along with blood vessels. All vertebrates have spinal and cranial nerves associated with the brain and spinal cord. Also many systems

cortex has four lobes – the frontal lobe‚ the parietal lobe‚ temporal lobe‚ and the occipital lobe (“Brain Structures and their Functions‚” n.d.; “Frontal Lobe - The Brain Made Simple‚” n.d.). The frontal lobe performs executive functions. These functions include initiation‚ inhibition‚ purposive action‚ volition‚ planning‚ reasoning‚ problem solving‚ parts of speech‚ flexibility‚ self-monitoring and self-regulation. It is used in making decisions and thinking. The frontal lobes are needed to complete

reported to the researcher that they felt as if their body was physically somewhere else in the room. This caused the researches to refer back to the MRI which revealed that the temporal and parietal lobes are involved in spatial perception. However‚ instead of finding direct information related to those lobes and body perception‚ they found that the hippocampus actually played an important role. Located in the hippocampus are GPS cells and neurons which are better known by the researchers as “place
