what an excellent question

comment location of the center surround receptive fields for retinal ganglion cells
yes. photoreceptors provide input to multiple ganglion cells. photoreceptor input to ganglion cells only comes indirectly via bipolar cells.

comment location of the center surround receptive fields for retinal ganglion cells
and yes, the photoreceptors providing input to a ganglion cell will tend to be arranged in a circle

comment location of the center surround receptive fields for retinal ganglion cells
the receptive field of each ganglion cell will be different. some have receptive fields that cover the entire visual field, but most have receptive fields that only include a small portion of the visual field.

comment what is the exact definition of a receptive field ?
the receptive field includes all properties of the stimulus that determine a neuron's response. the sensory area is one such property of the stimulus. other properties might include intensity, frequency, duration, etc. the receptive field is the subspace of the entire multi-dimensional sensory space that a neuron responds to.

comment How do we learn to count syllables?
it's really not about linguistics at all. its about language learning, which is very very on topic.

comment Text-to-brain literature?
i wouldn't really call that experiment "implanting" information. it's more like artificially reactivating a memory in a different context.

do you have any evidence of this or is it entirely anecdotal?

comment Text-to-brain literature?
current state of the art in brain-computer interfaces is limited to a few bits of bandwidth no matter the modality of the information.

comment Text-to-brain literature?
the serious answer is that we can't do text-to-brain or brain-to-text because we have next to no idea how the brain represents text.

comment Text-to-brain literature?
yeah it was a joke. the easiest way to get text-to-brain is by showing a person written words or by saying words out loud to someone.

comment In what ways can neurons fire randomly?
ironically, the figure you bring in implies that neurons are unlikely to fire randomly in vivo!

comment Where can I find good references about the neuronal connections in various areas in the cortex?
yes, normally its done by injecting a retrograde tracer (rabies) into an area and seeing which areas express the fluorescent protein that the rabies virus was carrying

comment Why are autistic people more likely to be savants than nonautistic people?
it's certainly not the case that "lacking an ability is what defines somebody to be autistic". people have a wide range of abilities, and each individual has a particular combination of abilities. autism is not simply a deficit of ability. it is a particular combination of assets and deficits.

try shepherd: the synaptic organization of the brain.
