1. Biological psychologists are gaining a better understanding of our experiences of sights and sounds‚ meanings and memories‚ pain and passion. Franz Gall invented phrenology‚ a popular theory that claimed that bumps on the skull reveal our mental abilities and our character traits. Although wrong‚ this information revealed that various brain regions have specific functions. 2. A neuron consists of a cell body and branching fibers:The dendrite fibers receive information from sensory

The two visual systems hypothesis talks about the processing of the visual information in two different routes in the brain (van Polanen & Davare‚ 2015). This idea was first introduced in 1982 when Leslie Ungerleider and Mortimer Mishkin described experiments that distinguished two streams that served different functions(Melvyn A. Goodale‚ 1998). They used the method know as ablation or also called lesioning. Using both recordings from neurons and ablation‚ they found that properties of the ventral

muscles. The largest part of the brain is the cerebrum. Underneath the cerebrum lies the brainstem‚ and behind that sits the cerebellum. The outmost layer of the cerebrum is called the cerebral cortex‚ which has four lobes. There is a frontal lobe‚ parietal lobe‚ temporal lobe‚ and occipital lobe. The brain develops from three sections known as the forebrain‚ midbrain‚ and hindbrain. There are two hemispheres‚ the left and the right. These two hemispheres are connected by a bundle of nerve fibers called

example‚ that as you are reading this article‚ you are eating a sandwich. As you are reading‚ the frontal lobes in your cerebral cortex are engaged in thinking and reasoning. You are enjoying your delicious sandwich thanks to your parietal lobes‚ which are responsible for taste‚ texture and smell of food. The occipital lobes help to process how you see the words on this page‚ and the temporal lobes help you process what you hear—like the crunch of your sandwich and the rustle of the page. Brain Myth

In a way it’s the world’s most powerful computer because it can process tasks at lightning speeds and simultaneously be in control of our reflexes and every other voluntary and involuntary functions. It is the most important and complex organ as well as our core for learning At the point of birth‚ the brain weighs an average of
