spinal cord. Both the brain and spinal cord are protected by three layers of connective tissue called the meninges. Within the central nervous system is a system of hollow cavities called ventricles. The network of linked cavities in the brain (cerebral ventricles) is continuous with the central canal of the spinal cord. The ventricles are filled with cerebrospinal fluid which is produced by specializedepithelium located within the ventricles called the choroid plexus. Cerebrospinal fluid surrounds

cells that detect sensory information. The sensory receptors then initiate neural impulses. Sensation occurs when the neural impulses arrive at the cerebral cortex. Neural impulses that begin in the optic nerve are sent to the visual areas of the cerebral cortex‚ and we see objects. Each person’s unique perception results from how the cerebral cortex interprets the meaning of the sensory information. Sensory adaptation: brain filters out redundant‚ insignificant information.

and that there is no room for freedom. Is the argument against determinism of all behavior a lost cause? All is not lost‚ as studies emerging from neuroscience elucidate evidences of free will residing in the brain‚ specifically the prefrontal cortex (Udell‚ 2009; de Jong‚ 2011). Higher-order functions of one’s behaviour which includes planning‚ reasoning and even lying is attributed to it (Karim et al.‚

involve lying awake but relaxed within a quite environment. Even though cognitive functions might not seem necessary in this scenario the brain‚ especially the cerebral cortex‚ is not able to rest but rather remains semi-alert in a state of "quiet readiness" . Certain stages of sleep are needed for the regeneration of neurons within the cerebral cortex while other stages of sleep seem to be used for forming new memories and generating new synaptic connections. The effects of sleep deprivation on behavior

What is Biological Psychology? It is the study of the physiological‚ evolutionary‚ and developmental mechanisms of behavior and experience. It is synonymous with the terms biopsychology‚ physiological‚ and behavioral neuroscience. Much of biological psychology is devoted to studying brain functioning. Physiology is the study of body processes- the dynamic of tissue and organ system of the body. It is the study of the physiological basis of human and animal behavior. Areas of Biological

The hair cells are moved by the sound waves and become receptors for the primary auditory cortex. The cortex then processes the sounds into an interpretation. (University of Phoenix‚

Chapter 3 The Biological Bases of Behavior Communication in the Nervous System * Nervous Tissue: The Basic Hardware * Neurons are individual cells in the nervous system that receive‚ integrate‚ and transmit information. * The soma‚ or cell body‚ contains the cell nucleus and much of the chemical machinery common to most cells. * Dendrites are the parts of a neuron that are specialized to receive information. * The axon is a long‚ thin fiber that transmits signals
