SUMMARYAt any one time, animals are simultaneously bombarded with many sensory stimuli, but they typically choose to respond to only a few of them. We used multidimensional analysis to determine the behavioral responses of six species of leeches to s

Retrograde signaling from target tissues has been shown to influence many aspects of neuronal development in a number of developmental systems. In these experiments using embryonic leeches (Hirudo medicinalis), we examined how depriving a neuron of c

Glial cells can respond with membrane potential changes during electrically stimulated neuronal activity (Kuffler, Proc R Soc Lond B 168:1-21, 1967; Orkand, Oxford University Press, 1995). Their role in contributing to, or controlling, neural circuit

The ontogeny of behavior in an organism must reflect developmental events in the nervous system, and it thus provides a noninvasive measure of neuronal development. This approach may be particularly fruitful in the medicinal leech because the neurona

We present a description of the last half of embryonic development in the European medicinal leech, Hirudo medicinalis, based entirely on externally visible morphological features, and establish reliably observable stages during that development. Emb

The serotonergic Retzius neurons of the leech midbody ganglia respond in a complex manner to pressure pulses of acetylcholine (ACh) applied onto their soma with a fast depolarization followed by a slower hyperpolarization and an additional delayed lo

The swimming behavior of the leech depends upon the level of serotonin in its blood stream: the higher the level, the more likely the leech is to swim. Serotonin is contained in Retzius cells, segmentally paired neurons, which release enough of this
