The establishment of ordered neuronal connections is supposed to take place under the
control of specific cell adhesion molecules (CAM) which guide neuroblasts and axons to …

Major themes in neuroethology concern the specificity of key stimuli, neurones tuned to such
stimuli, and the release of corresponding behaviour. Neurobiological data from the analysis …

“Sign stimuli” elicit specific patterns of behavior when an organism's motivation is
appropriate. In the toad, visually released prey-catching involves orienting toward the prey …

Activity-independent and activity-dependent mechanisms work in concert to regulate
neuronal growth, ensuring the formation of accurate synaptic connections. CPG15, a protein …

Almost all vertebrates are capable of recognizing biologically relevant stimuli at or shortly
after birth, and in some phylogenetically ancient species visual object recognition is …

Intermediate constructs are required as bridges between complex behaviors and realistic
models of neural circuitry. For cognitive scientists in general, schemas are the appropriate …

In 3-eyed frogs, afferents from 2 eyes converge on an optic tectum that normally receives
input from only 1 eye. This produces an interdigitating series of stripes, resembling the …

In the grass frog Rana temporaria, various classes of tectal neurons were identified by
means of intracellular recording and iontophoretic staining using potassium-citrate/Co 3+ …

Excitatory postsynaptic field potentials (termed U 1 and U 2 waves) were extracellularly
recorded from superficial layers of the frog optic tectum in vitro following stimulation of the …

A total of 47 tectal neurons of the weakly electric fish, Eigenmannia, were studied
physiologically and labelled by intracellular injection of Lucifer Yellow. With the exception of …
