Only quite recently has it become technically possible to record, from elec trodes attached to the scalp, the human brain's electrical responses to sensory stimulation. The core of this book is a critical survey of endeavours to use these electrical responses (called evoked potentials) as tools in attempts to discover the ways in which the brain first processes incoming sensory information and then forms internal representations of features ofthe external world. Buttressed by quantities of undeniably sloppy evoked potential research there are some who would dismiss out of hand the recording of evoked potentials as being comparable to 'holding an oscilloscope probe 6 feet in diameter up to a computer and pronouncing from the resultant waveform on the underlying structure and function'; many would contrast the scientific value of recording the activities of single nerve cells with microelectrodes. However, although it is certainly true that the brain may indeed function in a way which would not be susceptible to the approaches of the evoked potential researcher it might equally well resist the stratagems of the single-cell man. If, for example, the neural correlate of some sensation were the state of some large population of nerve cells, then the present-day researcher who records in great detail the activity of one single cell or of a very few cells would be faced with a major problem in trying to see the forest for the trees."

In this quarter-century update of Leo Tolstoy: An Annotated Bibliography of English Language Sources to 1978, authors David and Melinda Egan list the more than 1,200 books, essays, articles and doctoral dissertations written about the great Russian author from 1978 to 2003 (the 175th anniversary of Tolstoy's birth). In the twenty-five years since the first volume, there has been a remarkable growth in Tolstoy scholarship, including significant developments in feminist, psychological, linguistic, and intertextual studies. Most important, a number of seminal works have emerged which challenge the long-established critical view that Tolstoy was not one writer but two - Tolstoy the artist, who wrote the great classics War and Peace and Anna Karenina, and Tolstoy the moralist and sage, who, during the last three decades of his life, wrote didactic works to propagate his religious, moral and ethical views. The book provides a comprehensive list of English language studies of Tolstoy's life, art, thought and influence in order to promote awareness of and access to those works that have been written about him since 1977. The authors also include descriptive (non-critical) annotations for the vast majority of sources, allowing users to determine which studies they might find particularly valuable. Divided into nine sections, the book addresses Tolstoy's novels, the major components of his non-literary life, and his legacy to the world. The book also includes a subject index of several hundred headings to help users navigate their way through its principal sections.
