Each has its own skills associated with that specific areas (e.g. thinking is generally associated with the frontal cortex whilst vision with the occipital lobe; the frontal lobes are associated with motor control, speech, abstract thought, and sense of self, whilst the parietal lobes contain bodily sensations and the temporal lobes record hearing). Likewise each hemisphere has its specific expertise too with the analytical left containing speech, mathematical skills, or language and the right being largely nonverbal and holistic. None of these are exclusive to one side; rather they seem to prefer one side to the other. Observation of association of capabilities to specific neural region has partially been discovered by cutting the corpus colloseum that connects the brain thus 'splitting' the two hemispheres.
The brain can be further divided into the three regions of the forebrain (the most recent part), midbrain, and hind brain (the most primitive and oldest region). The cortex (i.e. forebrain) contains our thinking apparatus, whilst the midbrain and hindbrain (otherwise known...
These include:
The medulla that contains centers essential for reflex control of breathing, heart rate, and other vegetative functions; the cerebellum that maintains posture and muscle control; and the reticular formation that directs motor and sensory messages. Other parts include the thalamus that carried sensory information to the cortex; the hypothalamus that controls eating, sleep, body temperature and other basic motives and behavior; and the limbic system, which is the seat of emotion. Here we have that famed organ called the amygdala that drives happiness, sadness, fear and so forth, as well as the hippocampus that is responsible for memory.
Finally, we have the endocrine glands - a chemical communication system within the body -- that regulate and transmit hormones through the body, the hormones, in turn, effecting moods, behavior, and personality. Most of the endocrine glands are influenced by the pituitary, which is, in turn, controlled by the hypothalamus (both located in the brain).
Neurons This is how I would explain the electro-chemical interaction between neurons to a friend. Imagine standing in a giant room with a large number of other people -- each of you are holding your arms out to either side of your body, like Leonardo Da Vinci's drawing of "Vitruvian Man." The giant room corresponds the brain and the nervous system, and you and the other people are each individual neurons. You
Bacterial Toxins & Damage to Neurons Which bacterial toxins have negative impacts on the human body? This paper reviews those toxins and their effects on human functions. Clinical Diseases Professor F.H. Kayser explains that "Exotoxins" are pathogenic bacteria that are capable of producing a "variety of toxins that are either the only pathogenic factor" in the onset of diseases like diphtheria, tetanus and cholera, or if they aren't the only factor they are
As part of the experiment, another person entered the study area and expressed feelings of anger at the researcher for some time and at other times remained neutral. Later the researchers found that children who had witnessed the angry person were less likely to play with the toy compared to the children who had witnessed the neutral person. Also the researchers found that even the children who had seen
Its [mylelin insulation] growth enables a baby to gradually hold up its head, and its destruction by diseases such as multiple sclerosis causes severe impairment" (Chen 2009). Researchers have also found that both brain tumors and neurodegenerative diseases, such as Alzheimer's disease may be the result of problems with glia cells. Clearly, glia "are more than mere support cells that cater to the needs of neurons" and a "dynamic
Imagery and Cognitive Mapping and Their Common Applications Imagery and its applications Humans are capable of imagining moving without actually moving in real life. Studies making use of functional magnetic resonance imaging (fMRi) reveal that the same Motor Imagery (MI) part activated during real movement is also activated during imagination. Perhaps similar visual inputs lead to the activation of mirror neurons in the course of observing an action; internal inputs also
Mirror Neurons in the Context Of Cognitive Mapping There is much controversy with regard to the degree to which vision is tied to cognition, especially when considering the way that mirror neurons can affect the way a person thinks and can influence the respective individual to have a particular view of the surrounding environment. The contemporary society has a very complex understanding of how the visual system works and yet people
