Expression of the crustacean pyloric pattern generator in the intact animal

摘要: 1. InJasus lalandii the activity of central pattern generator pyloric motor output (the CPG) has been studied in intact free animals by electromyographic recording muscles (Fig. 2). 2. Two patterns (pattern 1 and 2) can be observed. Each corresponds to a specific behavioural situation: is only observed unfed lobsters feeding invariably produces switch from 2 3). 3. The two differ period cycle 4), burst duration constrictors 5), latency firing 6) phase 7). Correlation between constrictor weak strong 8). 4. The recorded vitro preparations when stomatogastric ganglion (i.e. connected more rostral commissural ganglia 9). 5. At least 1, cycling occur dilators (known as pacemakers are silent 10). 6. For these reasons, we concluded that oscillator could participating organization output. However, synaptic relationships which exist neurones cannot neglected 11) this suggests that, animal, organized cooperation premotor oscillator.
