The Twenty-Second British Commonwealth Lecture, “Aeronautical Research in India”, was given by Dr. S. Dhawan, MA, BSc(Eng), MS, FRAeS, Director of the Indian Institute of Science, Bangalore, on 3rd November 1966. The Chair was taken by the President, Mr. A. D. Baxter, MEng, FRAeS, and the distinguished audience included His Excellency Dr. J. Mehta, High Commissioner for India.Before the Lecture the President introduced Lord Caldecote, DSC, MA, FRAeS, immediate Past President of the Society of British Aerospace Companies Limited, who presented the four SB AC Scholarship Awards for 1966 to the recipients.Introducing the Lecturer, Mr. Baxter said that the British Commonwealth Lecture had been established immediately after the Second World War to foster interest and understanding in aeronautical developments between Great Britain and her partners in the Commonwealth. He thought that object had been successfully achieved by the efforts of a long and distinguished list of lecturers, both from home and overseas; now they were to add another distinguished name to that list. Dr. Dhawan had taken his first degree in mathematics and physics at Lahore in 1938; in 1941 he obtained his MA from the Punjab University and, from the same university, his BSc in Engineering in 1944. After a period as an Assistant Supervisor with the Hindustan Aircraft Company, he was selected by the Government of India for advanced studies abroad in aeronautics. Dr. Dhawan had gone to the United States where he took a Masters Degree in Aeronautics at the University of Minnesota and a PhD in Aeronautics at the Californian Institute of Technology. Returning to India in 1951, he joined the Department of Aeronautics at the Indian Institute of Science, becoming Assistant Professor in 1952 and Professor and Head of the Department in 1955 and, since 1963 Director of the Institute.

1. We studied neuronal activity in the supplementary eye field (SEF) and frontal eye field (FEF) of a monkey during performance of a conditional motor task that required capturing of a target either with a saccadic eye movement (the saccade-only condition) or with an eye-hand reach (the saccade-and-reach condition), according to visual instructions. 2. Among 106 SEF neurons that showed presaccadic activity, more than one-half of them (54%) were active preferentially under the saccade-only condition (n = 12) or under the saccade-and-reach condition (n = 45), while the remaining 49 neurons were equally active in both conditions. 3. By contrast, most (97%) of the 109 neurons in the FEF exhibited approximately equal activity in relation to saccades under the two conditions. 4. The present results suggest the possibility that SEF neurons, at least in part, are involved in signaling whether the motor task is oculomotor or combined eye-arm movements, whereas FEF neurons are mostly related to oculomotor control.

We make a saccadic eye movement once every few hundred milliseconds; however, the neural control of saccade execution is not fully understood. Dynamic, moment-by-moment variations in saccade velocity are typically thought to be controlled by neurons in the lower, but not the upper regions of the brainstem. In a recent report, Smalianchuk et al. (Smalianchuk I, Jagadisan UK, Gandhi NJ. J Neurosci 38: 10156–10167, 2018) provided strong evidence for a role of the superior colliculus, a midbrain structure, in the instantaneous control of saccade velocity, suggesting the revision of long-standing models of oculomotor control.
