What does it mean for neurons to be 'more broadly tuned'?

Tuning is a property found in many neurons in many areas of the brain. It refers to how the neuron responds (usually measured as its firing rate) to different stimuli. If a neuron is tuned to a particular property of a stimulus, it will have different responses to stimuli that have different values of that property. read more

For a cell to be"more broadly tuned" generally means that its tuning curve is wider. That is to say, it has higher responses to a wider range of values of the property it is tuned for. So in the orientation example, the cell would have a higher response to the diagonal bars. read more

Neuronal tuning can be strong and sharp, as observed in primary visual cortex (area V1) (but see Carandini et al 2005 ), or weak and broad, as observed in neural ensembles. Single neurons are hypothesized to be simultaneously tuned to several modalities, such as visual, auditory, and olfactory. read more
