Recent national reports call for increasing the quantitative acumen of biology students. The BioSQuaRE represents an assessment tool based on such reports. The iterative development of the instrument by science and mathematics faculty in collaboratio

Higher-order projection interneurons that function in more than one behavior have been identified in a number of preparations. In this study, we document that stimulation of cell Tr1, a previously identified trigger interneuron for swimming in the me

In this study we examined whether the foraging for artificial blood affected the behavioral responsiveness of leeches to electrical stimulation of the body wall. After foraging for artificial blood, electrical stimulation of the posterior end of the

Stimulation of a trigger interneuron of an isolated nerve cord preparation of the medicinal leech, Hirudo medicinalis, sometimes leads to swimming; sometimes it does not. The known synaptic interactions in the swim-initiating pathway do not adequatel

One important goal of introductory biology laboratory experiences is to engage students directly in all steps in the process of scientific discovery. Even when laboratory experiences are built on principles discussed in the classroom, students often

Since the experiments of Nicholls and Baylor, the initial characterization of identified neurons has provided significant insight into the circuitry transforming mechanosensory input into the motor output of swimming. From physiological characterizat

Stimulation of a trigger interneuron of an isolated nerve cord preparation of the medicinal leech, Hirudo medicinalis, sometimes leads to swimming; sometimes it does not. We investigate signals transmitted in the ventral cord of the leech after stimu

Previous physiological and pharmacological evidence has suggested a neurotransmitter role for the excitatory amino acid glutamate in the leech central nervous system (CNS). In the present study, we sought to localize glutamate receptor (GluR) subunit

Antagonists were used to investigate the role of the excitatory amino acid, L-glutamate, in the swim motor program of Hirudo medicinalis. In previous experiments, focal application of L-glutamate or its non-NMDA agonists onto either the segmental swi

Leech swimming is produced by the antiphasic contractions of dorsal and ventral longitudinal muscles that travel rearward along the animal and propel it forward. Research over the past three decades has focused on identifying the underlying neuronal
