Neurochemical-neuroendocrine systems in the brain controlling macronutrient intake and metabolism

Article Abstract:

Neurochemical and neuroendocrine signals coming from various peripheral organs and regions of the central nervous system are responsible for the regulation of the body's energy balance, nutrient stores, weight and nutrient intake. These signals are integrated by the hypothalamus through a variety of neurochemical and neuroendocrine systems involving the coordination of hormones, nutrients, amino acids, peptides and steroids. These systems in turn affect specific behavioral and physiological processes relating to macronutrient intake and metabolism. Disruptions in the normal functioning of these systems have been linked to alterations in normal feeding patterns.

A multidisciplinary approach to consciousness: the mind-brain problem and conscious-unconcious processing

Article Abstract:

The Ciba Foundation Symposium number 174 on Experimental and Theoretical Studies of Consciousness gathered philosophers and scientists to determine the possibility of adopting a multidisciplinary approach to issues sorrounding the brain and consciousness. Specifically, the symposium sought to define the nature of mind-brain interactions. Psychologists discussed three major ideas, namely the unity of consciousness, brain and consciousness dissociations and the dissociations between conscious and unconscious processes.

Monotremunculi and brain evolution

Article Abstract:

Recent research indicates the likelihood of independent evolution of the somatosensory system of monotremes. The presence of three to four somatosensory maps in monotremes and advanced eutherians is an instance of parallel evolution. Similarly, the presence of parietal ventral area in monotremes and of second somatosensory area in primitive therians bolsters the notion of parallelism in evolution of somatosensory cortex.
