Converging on olfactory white

Early telencephalic migration topographically converging in the olfactory cortex.

Neurons that participate in the olfactory system arise in different areas of the developing mouse telencephalon. The generation of these different cell populations and their tangential migration into the olfactory cortex (OC) was tracked by tracer injection and in toto embryo culture. Cells originating in the dorsal lateral ganglionic eminence (LGE) migrate tangentially along the anteroposterio...

Converging on Program Simplicity

A remark on the converging-input converging-state property

Suppose that an equilibrium is asymptotically stable when external inputs vanish. Then, every bounded trajectory which corresponds to a control which approaches zero and which lies in the domain of attraction of the unforced system, must also converge to the equilibrium. This “well-known” but hard-to-cite fact is proved and slightly generalized here.

Converging Hands or Converging Minds?

Interlocutors sometimes repeat each other’s representational hand gestures. We investigated if this is a case of direct mimicry of form, or whether perceiving a gesture gives rise to a semantic representation, which subsequently informs gesture production. For this we used an interactive route description task, in which a confederate’s gestures indicated the route in either the vertical or the ...

Converging Circuits Mediate Temperature and Shock Aversive Olfactory Conditioning in Drosophila

BACKGROUND Drosophila learn to avoid odors that are paired with aversive stimuli. Electric shock is a potent aversive stimulus that acts via dopamine neurons to elicit avoidance of the associated odor. While dopamine signaling has been demonstrated to mediate olfactory electric shock conditioning, it remains unclear how this pathway is involved in other types of behavioral reinforcement, such a...
