The structural and functional properties of the visual system are disrupted in mutant animals lacking beta2 subunit nicotinic acetylcholine receptor. In particular, eye-specific retinogeniculate projections do not develop normally these mutants. It is widely thought that developing retinas beta2(-/-) mutants manifest correlated activity, leading to notion retinal waves play an instructional role formation projections. By multielectrode array recordings, we show here have robust during Unlike...

Deep learning (DL) has been widely applied to many domains. Unique challenges in engineering DL systems are posed by the programming paradigm shift from traditional systems, and performance is one of challenges. Performance problems (PPs) can cause severe consequences such as excessive resource consumption financial loss. While bugs have extensively investigated, PPs hardly explored. To bridge this gap, we present first comprehensive study i) characterize symptoms, root causes, introducing...

Epibatidine (EPI), a potent cholinergic agonist, disrupts acetylcholine-dependent spontaneous retinal activity. Early patch-clamp recordings in juvenile ferrets suggested that EPI blocks all ganglion cell (RGC) action potentials when applied to the retina. In contrast, recent experiments on developing mouse relied multielectrode array (MEA) reported application decorrelates activity of neighboring RGCs and eliminates waves while preserving spiking many neurons. The different techniques used...
