Abstract : Several directions have been followed toward the attainment of our research goals. We have continued recording in the untrained monkey, looking at arousal related changes in spontaneous and evoked thalamic activity, as well as, the effects of various drugs on these responses. We are now recording the responses of thalamic somatosensory neurons in behaviorally trained animals, looking at response modulation during two attentional paradigms, including shifts in arousal. Preliminary experiments have been conducted to develop methods for examining the underlying mechanisms of thalamic modulation. We are continuing to update and validate our computerized stereotaxic atlas of the green monkey brain. We have also developed a unique computer program for the acquisition (PETH) and statistical analysis (HISTSAT) of perievent time histograms. Some of the results in this report have been or will be communicated at scientific meetings, published or are in press. Keywords: Nerve transmission, Cerebral cortex.
