 Amygdala: almond shaped mass of nuclei involved in emotional responses, hormonal secretions and memory  Cingulate Gyrus: a fold in the brain involved with sensory input concerning emotions and the regulation of aggressive behavior

 Mainly concerned with homeostasis  Hunger, thirst, response to pain, levels of pleasure, sexual satisfaction, anger, aggressive behavior  Regulates function of autonomic nervous system  Regulates pulse, blood pressure, breathing, arousal in response to emotional circumstances

 Fornix: a band of nerve fibers that connect the hippocampus to the hypothalamus  Hippocampus: acts as a memory indexer sending memories out to the appropriate part of the cerebral hemisphere for long-term storage and retrieving them when necessary

 Olfactory Cortex: receives sensory information from the olfactory bulb and is involved in the identification of odors  Thalamus: a large, dual lobed mass of grey matter cells that relay sensory signals to and from the spinal cord and the cerebrum

 The limbic system is considered to be responsible for different emotions. Based off of the different theories on emotions, memory can effect emotion. Because the hippocampus, where the memories are stored, is a part of the limbic system as well as the amygdala, which is responsible for feelings of anger and rage, and the hypothalamus, which secretes hormones such as dopamine (responsible for a happy or excited feeling); the limbic system is often thought of as the center for emotion. The cingulate gyrus also takes in sensory info for emotion.

 Two of the main structures believed to be involved in the formation of memories, the hippocampus and amygdala, are within the confines of the limbic system.

 The limbic system is responsible for “reward” and therefore thought to be connected to motivation. The limbic system often releases hormones to back things that would ensure survival. For instance, sex is linked with the limbic system as well as food, which releases hormones that cause pleasure because food and sex are two of the main drives behind survival.

 The olfactory cortex is located in the limbic system, which involves recognition of scents and because smell is often associated with memory; the olfactory cortex is an important part of the limbic system.
