Tīmeklis2002. gada 1. janv. · The basal ganglia are now considered as integral parts of larger, distinct circuits involving the cerebral cortex and thalamus, and they have been implicated in a wide variety of motor functions, including the planning, ... The “shared CPGs” hypothesis postulated by Grillner 32 to explain lamprey movement may also … TīmeklisThe lamprey swims by producing waves of curvature from anterior to posterior of the body, alternately on each side, due to contraction of myotomal longitudinal muscle fibres. Since the waves are short, progress by swimming is slow. Endoskeleton: The skeleton is wholly cartilaginous. TīmeklisThe thalamus is a key structure in the mammalian brain, providing a hub for communication within and across distributed forebrain networks.
