Finding cross-columnar observables in barrel cortex

[john-judge]

2 main excitatory neuronal classes within L4 of somatosensory / visual cortices are spiny stellate neurons (SSNs) and star pyramid neurons (SPNs). At least ~5% of neurons project directly into neighboring barrels may create multiwhisker surround RFs Egger et al 2008

• Whiskers deflected in same direction <=(?)=> interbarrel feed-forward excitation in spiny L4 neurons
• Intrabarrel RF properties (e.g. whisker deflection angle) <=(?)=> directional tuning info transmitted between columns
