Study Notes
-
The limbic system is responsible for balancing body fluids and body temperature. It includes the amygdala and hippocampus.
-
The amygdala is involved in fear, excitement, arousal, and emotional memories. Damage to the amygdala can result in problems with detecting fears.
-
The hippocampus is responsible for forming and storing autobiographic memories and spatial memories. Damage to the hippocampus can lead to amnesia, leaving old memories intact but preventing the formation of new ones.
-
The brain stem connects the cerebral cortex and spinal cord and controls basic bodily functions. It evolved 500 million years ago and includes the midbrain and hindbrain.
-
The midbrain is responsible for communication between the hindbrain and the forebrain and handles sensory information from the eyes and ears, triggering reflexes. The reticular activating system (RAS) in the midbrain plays a role in alertness, sleep cycles, and attention.
-
The spinal cord runs from the brain stem to the back and is responsible for relaying signals between the brain and the body. It is protected by the vertebrae and is the center of reflexes.
-
The endocrine system consists of glands that release hormones, which influence particular organs and help regulate emotions. The pituitary gland controls other glands in the body and is controlled by the hypothalamus.
-
The adrenal glands release adrenaline and cortisol, which are responsible for emotional arousal and stress responses, respectively. Anxiety disorders are associated with high cortisol levels.
-
The sexual reproductive glands, including the testes in males and ovaries in females, release hormones that play a role in sexual development and function.
-
Brain mapping methods, such as phrenology, electroencephalography (EEG), and neuroimaging techniques (computed tomography (CT) and magnetic resonance imaging (MRI)), have been used to understand the relationship between the brain and behavior. Phrenology, which relied on the shape of the skull to predict personality traits, was found to be inaccurate. Neuroimaging techniques, such as CT and MRI, allow scientists to see brain structure and function. EEG can detect electrical activity in the brain but is not precise enough to pinpoint the location of brain activity.
