1A; 7B), the pyramidal tract (Fig.
In this manner, inactive cells are brought closer to threshold, enhancing their opportunity to firing together [ 29 30 31 ] . The extracellular resistance is the major determinant of field-effect strength [ 32 ] . Since the extracellular volume fraction in CA1 stradium pyramidal is only 12% compared with approximately 18% in CA3 and granule cells [ 33 ] , the CA1 pyramidal cells are particularly susceptible to field effects.
The γ frequency oscillations (30-100 Hz) are characteristic of responses to sensory input measured by cortical EEG [ 9 ] . In the hippocampal slice preparation, γ oscillations can be evoked by brief, high frequency tetanic stimuli to region CA1 [ 10 11 12 13 ] . The extracellular field potential response during these oscillations takes the form of a train of population spikes in stratum pyramidal at γ and β (15-30 Hz) frequencies [ 14 ] . Intracellular recordings during γ oscillations induced by tetanic stimulation reveal a slow membrane depolarization in conjunction with GABA A receptor-mediated inhibitory postsynaptic potentials [ 11 15 ] . This synaptic inhibition-based γ activity entrains action potential generation in pyramidal neurons, leading to the population spikes at γ band frequencies.
However, for example, we found NK-ir structures (the antibody used in this study principally recognizes NKA)(see specificity of the antiserum in Methods) in the human brainstem in the lateral cuneate nucleus and in the pyramidal tract, in which no SP-ir structure has been described in humans [ 24 25 26 27 ] . It is known that both neuropeptides, SP and NKA, are derived from the same precursor.
It is characterized by progressive gait and limb ataxia, lack of tendon reflexes, dysarthria and pyramidal weakness in inferior limbs [ 30].
