Feeding regulation involves multiple peripheral and brain mechanisms (12). Chemical signaling is a pivotal mechanism. One class of endogenous feeding-regulatory substances is represented by cytokines. In this article, various issues of feeding inhibition by cytokines are discussed, including behavioral, cellular, and molecular mechanisms. The description will focus on data obtained with interle...

Artiodactyls employ selective brain cooling (SBC) regularly during experimental hyperthermia. In free-ranging antelopes, however, SBC often was present when body temperature was low but absent when brain temperature was near 42°C. The primary effect of SBC is to adjust the activity of the heat loss mechanisms to the magnitude of the heat stress rather than to the protection of the brain from th...

“reflex circuits.” Each neural circuit contains an afferent neuron that carries electrical activity from the periphery to a center of integration, either a ganglion or a specialized region of the brain. After afferent signals are processed, information flows back to the periphery via motoneurons to modify behavior. Thus afferent neurons were thought to be the sensors of the digestive state. Sin...

The modern view of the mammalian bloodbrain barrier (BBB) has shifted from a purely anatomic concept to a more physiological and dynamic definition. Morphologically, the BBB is formed by specialized endothelial cells (ECs) lining the intraluminal portion of brain capillaries. These ECs are characterized by specialized regions of intercellular contact (tight junctions) that prevent leakage of bl...

Neurite growth and regeneration in the adult central nervous system (CNS) is extremely limited. An important factor contributing to these restrictions is specific growth inhibitory proteins associated with oligodendrocytes and CNS myelin. A major inhibitory factor is the antigen of a monoclonal antibody; the application of this neutralizing antibody to spinal cordor brain-lesioned adult rats in...
