BDNF and stroke disorder: According to the connections between the cortex and the striatum and the reduced capacity of BDNF synthesis by striatal neurons [39], BDNF loss in the striatum after stroke may be linked to the stimulation or the inhibition by the lesion of BDNF axonal transport from the striatum towards the cortex or from the cortex to the striatum, respectively as BDNF can be transported in the axon in both anterograde and retrograde directions [39], [40].
