In the head region, the brain is represented by supra-oesophageal ganglion which supplies nerves to antennae and compound eyes. 1. 2. These findings suggest that in these invertebrates, PHI may play … Consciousness in a Cockroach The insect nervous system provides clues to attention, consciousness, and the origin of the brain. Three pairs of nerves originate from the supra-oesophageal ganglion—optic, antennary and labrofrontal nerves. When one subjects the cockroach to a puff of air, many of the cercal hairs bend in their sockets. The network of neurons acts as a central pattern generator.It is a model system for motor pattern generation because of the small number of cells, which are comparatively large and can be reliably identified. Sympathetic Nervous System: The autonomic or stomogastric or sympathetic or visceral nervous system of cockroach consists of some ganglia and their connectives. The predominant characteristics of the cockroach central nervous system (CNS) are its segmented nature and decentralization of control processes (Ganihar et al., 1994; Pipa & Delcomyn, 1981). It is produced by the fusion of three pairs of ganglia. The compound eyes are situated at the dorsal surface of the head. The thoracic and first five abdominal ganglia give off paired segmental nerves to appendages, muscles and other structures.

Nervous system of the cockroach (Periplaneta americana) can be recognized as a remarkably useful model preparation in multiple electrophysiological techniques, which allows to perform pharmacological tests on diverse levels of nervous system organization. In order to subdue the larger cockroach, the wasp injects venom directly into its central nervous system, inducing a long-term lethargy or “hypokinesia”. The brain or supra-oesophageal ganglia are a pair of large, closely apposed ganglia in the head.
