		Limbic system - the physiology of emotion, the visceral activity, the reception of olfactory impulses (whence rhinencephalic system).
		The zone of the limbic system referred to as hippocampus ensures contact or loss of contact with the external world; associates characteristics of various signal sources and sends them to the reward or penalty areas of the hypothalamus; is involved in motivation.
		The limbic system ensures the survival of the individual and of the species and determines adequate behavior to this purpose.

		The limbic system is a group of brain structures that are involved in various emotions such as aggression, fear, pleasure and also in the formation of memory.
		The limbic system is among the oldest parts of the brain in evolutionary terms: it can be found in fish, amphibians, reptiles and mammals.
		The limbic system is tightly connected to the prefrontal cortex.

	limbic
		The limbic system, interposed between the hypothalamus and the neocortex, mediates the accompanying emotions and is importantly involved in memory.
		Although the limbic system was originally thought to be primarily associated with the olfactory system (e.g., Broca), the main functions appear to be non-olfactory in nature.
		Structures generally included in the limbic system are: the cingulate and parahippocampal gyri, the hippocampal formation, the septal areas and at least portions of the amygdala.

	Paul MacLean's triune brain hypothesis
		The old mammalian brain residing in the limbic system is concerned with emotions and instincts, feeding, fighting, fleeing, and sexual behaviour.

	Integrating the body's four brains
		For millions of years prior to the upstart neocortex coming along, the regulation of the body’s systems was successfully carried out by the triumvirate of the enteric nervous system, reptilian brain, and limbic brain.
		When we talk about the interaction of nervous systems among mammals, we mean that the nervous systems of two people in relationship very definitely communicate with, inform, and change each other.
		We increase awareness of and responsiveness to the communication of the enteric nervous system and the reptilian and limbic brains.

	Limbic System (Site not responding. Last check: 2007-10-03)
		These structures are known as the Limbic system, and are a set of subcortical structures that form a border (or limbus) around the brain stem.
		Because the size of the limbic system is relatively constant in size across mammalian species, in contrast to the cortex which varies greatly in size, he concluded that the limbic system control primitive functions that all mammals share in common.
		Although one can easily speculate about a relationship between the limbic system and autistic behaviors, we should be conservative, because much of what we know comes from animal models in which the parts of the limbic system are damaged artificially.

	Endocrine System
		The endocrine system shares with the nervous system a role for control and coordination throughout the body.
		The nervous system is mostly thought of as dealing with very short term control (on a time scale of milliseconds to seconds), while the endocrine system, through hormones, may exert relatively short term (seconds to minutes) or long term (days to weeks) control.
		The endocrine system is important in the development and maintenance of the nervous system.

	Mind Over Matter Teacher's Guide - Introduction and Background
		The limbic system structures are involved in many of our emotions and motivations, particularly those that are related to survival, such as fear, anger, and emotions related to sexual behavior.
		The limbic system is also involved in feelings of pleasure that are related to our survival, such as those experienced from eating and sex.
		So, the pleasure circuit, which is known as the mesolimbic dopamine system, spans the survival-oriented brainstem, the emotional limbic system, and the frontal cerebral cortex.

	How and Why did we do this?
		The ultimate goal of the project was to produce a holographic representation of the human limbic system for the Image and Meaning conference at MIT in June 2001.
		Sketches of the limbic system are not rare, in fact, you can find one in almost any anatomical textbook produced for introductory psychology to advanced neuroanatomy.
		The results were promising, but they resembled more one of the early sketches of the limbic system which were intended to show only the basic shape and approximate relationship between the limbic structures, and not really appropriate for this project.

		The olfactory system actually begins in the roof of the nasal cavity.
		However, the sense of smell is heavily interconnected with all parts of the limbic system.
		The olfactory system disobeys a general rule of sensory systems - it does not have to pass through thalamus before reaching cortex.

	The Limbic System: The Seat of Consciousness in the Human Brain (Site not responding. Last check: 2007-10-03)
		The center of emotions in the brain can be found in the limbic system where the vast panoply of emotions is regulated through the release of excitatory and inhibitory neurotransmitters: Pleasure may be linked with chemical signals produced by the release of noradrenalin, and pain is associated with many neurotransmitters.
		In response to a variety of stimuli, emotions arise in the limbic system, travelling along neural pathways to the frontal lobes of the cortex, where feelings are monitored and interpreted.
