Willis was born on his parents' farm in Great Bedwyn, Wiltshire, where his father held the stewardship of the Manor. He was a kinsman of the Willys baronets of Fen Ditton, Cambridgeshire. He graduated M.A. from Christ Church, Oxford in 1642. In the Civil War years he was a royalist, dispossessed of the family farm at North Hinksey by Parliamentary forces. In the 1640s Willis was one of the royal Physicians to Charles I of England. Less grandly, once qualified B. Med. in 1646, he began as an active physician by regularly attending the market at Abingdon.
He maintained an Anglican position; an Anglican congregation met at his lodgings in the 1650s, including John Fell, John Dolben, and Richard Allestree. Fell's father Samuel Fell had been expelled as Dean of Christ Church, in 1647; Willis married Samuel Fell's daughter Mary, and brother-in-law John Fell would later be his biographer. He employed Robert Hooke as an assistant, in the period 1656-8; this probably was another Fell family connection, since Samuel Fell knew Hooke's father in Freshwater, Isle of Wight.
Willis lived on Merton Street, Oxford, from 1657 to 1667. In 1656 and 1659 he published two significant medical works, De Fermentatione and De Febribus. These were followed by the 1664 volume on the brain, which was a record of collaborative experimental work. From 1660 until his death, he was Sedleian Professor of Natural Philosophy at Oxford. At the time of the formation of the Royal Society of London, he was on the 1660 list of priority candidates, and became a Fellow in 1661. Henry Stubbe became a polemical opponent of the Society, and used his knowledge of Willis's earlier work before 1660 to belittle some of the claims made by its proponents.
Willis's work gained currency in France through the writings of Daniel Duncan. The Philosopher Richard Cumberland quickly applied the findings on brain anatomy to argue a case against Thomas Hobbes's view of the primacy of the passions. Willis's books, including Cerebri anatome and selected works in 5 volumes (1664) are listed as once in the library of Sir Thomas Browne. His son Edward Browne (physician), who was President of the Royal College of Physicians from 1704-1707 also owned books by Willis.
Willis later worked as a physician in Westminster, London, this coming about after he treated Gilbert Sheldon in 1666. He had a successful medical practice, in which he applied both his understanding of anatomy and known remedies, attempting to integrate the two; he mixed both iatrochemical and mechanical views. According to Noga Arikha
In 1667 Willis published Pathologicae cerebri, et nervosi generis specimen, an important work on the pathology and neurophysiology of the brain. In it he developed a new theory of the cause of epilepsy and other convulsive diseases, and contributed to the development of psychiatry. In 1672 he published the earliest English work on medical psychology, Two Discourses concerning the Soul of Brutes, which is that of the Vital and Sensitive of Man. Willis could be seen as an early pioneer of the mind-brain supervenience claim prominent in present day neuropsychiatry and philosophy of mind. Unfortunately, his enlightenment did not improve his treatment of patients, advocating in some cases to hit the patient over the head with sticks.
By his wife, Mary Fell, Willis had five daughters and four sons, of whom four children survived early childhood. After Mary's death in 1670, he married the widow Elizabeth Calley, daughter of Matthew Nicholas, in 1672: there were no children of this marriage.
He coined the term mellitus in diabetes mellitus. An old name for the condition is "Willis's disease". He observed what had been known for many centuries elsewhere, that the urine is sweet in patients (glycosuria). His observations on diabetes formed a chapter of Pharmaceutice rationalis (1674). Further research came from Johann Conrad Brunner, who had met Willis in London.
Browne Willis, the antiquary, was son of Thomas Willis (1658–1699), the eldest son of Thomas and Mary. Between 1724 and 1730, Browne Willis rebuilt St. Martin's Church on the site of the old Chantry Chapel of St. Margaret and St. Catherine at Fenny Stratford. He erected the church as a memorial to his grandfather Willis who lived in St. Martin's Lane in the parish of St. Martin-in-the-Fields in London and who died on St. Martin's Day, 11 November 1675.
