Competition between cold phenytoin and [3H]phenytoin binding was observed in normal human brain. Binding was observed in all areas examined. The highest number of sites was in the amygdala (a total of 717.71 fmol/mg protein) and the lowest in the Brodman area (BA) 4 of the motor cortex (153.91 fmol/mg protein) and cerebellar cortex (154.4 fmol/mg protein). In three areas, amygdala, cortex area BA 38 (inferior parietal lobe), and cortex area BA 8 (premotor cortex), two sets of binding sites were observed. In these areas the Kd for the higher affinity sites ranged from 35 to 116 nM, and for the lower affinity site, from 328 to 866 nM. In the four areas where only one binding site was observed the Kds ranged from 164 to 311 nM and the Scatchard plot was linear.

Median Nerve Stimulation

Spike timing-dependent plasticity (STDP) has been proposed as one of the key mechanisms underlying learning and memory. Repetitive median nerve stimulation, followed by transcranial magnetic stimulation (TMS) of the contralateral primary motor cortex (M1), defined as paired-associative stimulation (PAS), has been used as an in vivo model of STDP in humans. PAS-induced excitability changes in M1 have been repeatedly shown to be time-dependent in a STDP-like fashion, since synchronous arrival of inputs within M1 induces long-term potentiation-like effects, whereas an asynchronous arrival induces long-term depression (LTD)-like effects. Here, we show that interhemispheric inhibition of the sensorimotor network during PAS, with the peripheral stimulation over the hand ipsilateral to the motor cortex receiving TMS, results in a LTD-like effect, as opposed to the standard STDP-like effect seen for contralateral PAS. Furthermore, we could show that this reversed-associative plasticity critically depends on the timing interval between afferent and cortical stimulation. These results indicate that the outcome of associative stimulation in the human brain depends on functional network interactions (inhibition or facilitation) at a systems level and can either follow standard or reversed STDP-like mechanisms.
