Biopsychology as a Neuroscience (1-19)
What Is Biopsychology
- The human brain is a squishy, wrinkled, walnut-shaped hunk of tissue weighing about 1.3 kilograms. The human
brain is an amazingly intricate network of neurons (cells that receive and transmit electrochemical signals).
Neuroscience (the scientific study of the nervous system) may prove to be the brains ultimate challenge.
- Jimmie G (the main frozen in time) believed he was 19 not 49. He has good sensory, motor, and cognitive
abilities, he had one terrible problem: he forgot everything that was said or shown to him within a few seconds. He
was frozen in time, a mean without a recent past and no prospects for a future, stuck in a continuous present,
lacking any context of meaning.
- Thinking creatively is the corner stone to any science. Clinical (pertaining to illness or treat) considerations are
woven through the fabric of biopsychology. Much of what biopsychologists learn abut the functioning of the
normal brain comes from studying the diseased or damaged brain; and conversely, much of what biopsychologists
discover has relevance for the treatment of brain disorders.
Although the events that led to the evolution of the
human species can never be determined with certainty, thinking of the environmental pressures that likely led to
the evolution of our brains and behavior often leads to important biopsychological insights. This approach is called
the evolutionary perspective. An important component of the evolutionary perspective is the comparative approach
(trying to understand biological phenomena by comparing them in different species). Research has clearly
demonstrated that the adult brain is not a static network of neurons, it is a plastic (changeable) organ that
continuously grows and changes in response to the individuals genes and experiences.
- Biopsychology is the scientific study of the biology of behaviour, aka psychobiology, behavioral biology, or
Psychology is the scientific study of behaviour, all overt activities of the organism as
well as all the internal processes that are presumed to underlie them (eg. learning, memory, motivation, perception,
and emotion). D.O. Hebb developed the first comprehensive theory of how complex psychological phenomena,
such as perceptions, emotions, thoughts, and memories, might be produced by brain activity. Hebb based his
theory on experiments, clinical case studies, and logical arguments developed from observations of daily life.
Relation between Biopsych and other Neuroscience.
- Neuroanatomy is the stuffy of the structure of the nervous system. Neurochemisty is the study of the chemical
bases of neural activity. Neuroendocrinology is the study of interactions between the nervous system and the
endocrine system. Neuropathology is the study of nervous system disorders. Neuropharmacology is the study of
the effects of drugs on neural activity. Neurophysiology is the study of the functions and activities of the nervous
