The first brain cell of the body, a neuron, begins in the womb. On the forty-second day of life, the neuron begins to develop. During the next one hundred twenty days, the brain will develop approximately 100 billion neurons at a rate of 9,500 neurons per second. Additionally, about 60 days before birth, each neuron begins to establish connections with other cells. Unlike any other … Continue reading Brain Dominance
A reflex is something that is stereotyped in form, meaning that all members of a certain species will have that same reflex; reflexes can also be recognized in all normal members of a species. As reflexes are built in an organism, they do not need to be learned. Snakes, for example, are born with all of the reflexes they need for survival. They emerge from … Continue reading Reflexes v. Reactions
Although there are many different kinds of neurons in the nervous system, the same basic electrical principles underlie their function. Before we can get into the complexities of neuronal signaling, let us take a look at the electrical principles that are in play when the cell is at rest. When you look at a typical neuron, you can see that it has a variety of … Continue reading Resting Potential & Voltage
Biopsychology is a branch of psychology that deals specifically with how the brain and neurotransmitters act upon the body, influencing what we do, say, and feel. In other words, it is the biology of the mind. This field leans heavily on neuroscience and includes the study of the nervous system. Anatomy, physiology, and statistics are also essential in the study of biopsychology. Understanding the nervous … Continue reading Neural Communication
