Lanthanum damages learning and memory and suppresses astrocyte-neuron lactate shuttle in rat hippocampus.

abstract：:A magnetic stimulus applied to the human scalp over the motor cortex causes a short latency contraction of contralateral limb muscles. This is presumed to result from the indirect excitation of corticospinal neurons with monosynaptic connections to motoneurons. The excitability of these cortical neurons can be estimat...
