Notes: Summary Auditory-evoked responses in single neurons from rhesus monkey auditory cortex were measured under four relatively well defined behavioral and physiological conditions: (1) monkey awake and performing a simple auditory reaction time task; (2) monkey awake but not performing a task (State A); (3) monkey in a drowsy or Stage 1 sleep state (State B); and (4) monkey anesthetized with a short-acting nonbarbiturate anesthetic. For most units studied the response evoked by the auditory stimulus was greater in the performance condition than in the nonperformance condition. Similarly, evoked activity was usually greater in State A than in State B. Finally, evoked responses under anesthesia were usually weaker than those obtained in the unanesthetized animal. Some exceptions were noted in each case. Differences in response patterns and in rate versus intensity functions of neurons were also found to be associated with the behavioral and physiological state of the preparation. No significant changes in unit spontaneous activity associated with changes in behavioral or physiological condition were observed.

Notes: B-lymphocyte colonies were grown in semi-solid agar from mouse spleen or lymph node cells in the presence of mercaptoethanol with or without added sheep red cells. High levels of colony-forming cells were present in the spleen or normal mice and nu/nu (athymic) mice but colony-forming cells were rare in the thymus and not detected in activated T-lymphocyte populations. Colony-forming cells were θ-negative and most exhibited Fc receptors. Most colony-forming cells had the sedimentation velocity of small lymphocytes, were non-adherent and had a buoyant density similar to B-lymphocytes. Colony-forming cells were radiosensitive (Do 60 rads) and sensitive to cortisone. Colony formation was potentiated by the addition of adherent spleen cells or peritoneal macrophages. It is concluded that most cells forming B-lymphocyte colonies are themselves characterisable as B-lymphocytes.
