In the late 1960s and early 1970s David Marr produced three
astonishing papers in which he gave a detailed account of how the
fine structure and known cell types of the cerebellum, hippocampus
and neocortex perform the functions that they do. Marr went on to
become one of the main founders of Computational Neuroscience. In
his classic work 'Vision' he distinguished between the
computational, algorithmic, and implementational levels, and the
three early theories concerned implementation. However, they were
produced when Neuroscience was in its infancy. Now that so much
more is known, it is timely to revisit these early theories to see
to what extent they are still valid and what needs to be altered to
produce viable theories that stand up to current evidence. This
book brings together some of the most distinguished scientists in
their fields to evaluate Marr's legacy. After a general
introduction there are three chapters on the cerebellum, three on
the hippocampus and two on the neocortex. The book ends with an
appreciation of the life of David Marr by Lucia Vaina.
The prefrontal cortex makes up almost a third of the human brain,
and it expanded dramatically during primate evolution.
The Neurobiology of the Prefrontal Cortex presents a new theory
about its fundamental function. In this important new book, the
authors argue that primate-specific parts of the prefrontal cortex
evolved to reduce errors in foraging choices, so that our ancestors
could overcome periodic food shortages. This evolutionary
development laid the foundation for working out problems in our
imagination, which resulted in the origin of insights that allow
humans to avoid errors entirely, at least at times.
In the book, the authors detail which parts of the prefrontal
cortex evolved exclusively in primates, how its connections explain
why the prefrontal cortex alone can perform its function, and why
other parts of the brain cannot do what the prefrontal cortex does.
Based on an analysis of its evolutionary history, the book uses
evidence from lesion, imaging, and cell-recording experiments to
argue that the primate prefrontal cortex generates goals from a
current behavioural context and that it can do so on the basis of
single events. As a result, the prefrontal cortex uses the
attentive control of behaviour to augment an older general-purpose
learning system, one that evolved very early in the history of
animals. This older system learns slowly and cumulatively over many
experiences based on reinforcement. The authors argue that a new
learning system evolved in primates at a particular time and place
in their history, that it did so to decrease the errors inherent in
the older learning system, and that severe volatility of food
resources provided the driving force for these developments.
Written by two leading brain scientists, the Neurobiology of the
Prefrontal Cortex is an important contribution to our understanding
of the evolution and functioning of the human brain.

A successor to the acclaimed 'Neurobiology of the Prefrontal
Cortex', 'Understanding the Prefrontal Cortex' presents a careful
study of the anatomical connections in this brain region, showing
how each area and subarea of the brain has a unique pattern of
connections, and exploring the transformation that this area
performs - from its inputs to it outputs. The book starts with two
chapters of foundational material, before considering five
subdivisions of the prefrontal cortex, and looking at the
transformation that each one performs. Next it considers how the
prefrontal cortex interacts with the rest of the brain, including
not only cortical areas but also subcortical areas such as the
basal ganglia and cerebellum. The book ends with a final section in
which these principles are applied to the human brain. It starts by
discussing the expansion of the prefrontal cortex during human
evolution. It then considers how the human brain has co-opted
mechanisms that existed in our primate ancestors, and by providing
new inputs had extended them so as to support reasoning,
remembering events from the distant past and imagining events in
the distant future, the sense of self, language, the ability to
understand the mental states of others, and the ability to
cooperate and learn social and moral rules. Written by a leading
brain scientist, the book will be an important and influential
contribution to the neuroscience literature.
This book succinctly demonstrates how the brain's frontal lobe is
specialized for directing voluntary action. Using data from
monkeys, neurological patients, and normal subjects, the author
presents a flow diagram of frontal lobe operations at the systems
level. Topics include the various definitions of the term
"voluntary" in a neuropsychological context, how the motor cortex
provides a mechanism for the execution of voluntary behavioral
actions, and how the premotor areas play a role in the selection of
the movements to be performed. The text also shows how the
prefrontal cortex is engaged when the subject has to make new
voluntary decisions, and how the basal ganglia play a critical role
in response learning. The author considers how, in humans, the
prefrontal cortex has been refined to allow for trial-and-error
decision making, and how the premotor and prefrontal areas select
between verbal responses. Psychologists, neuropsychologists, and
neurophysiologists will all want to read this pathbreaking book.
Brain imaging has revolutionised the field of Psychology - once
more concerned with IQ tests, reaction times and questionnaires.
Most Psychology departments now have access to an MRI scanner -
some have even renamed themselves as departments of cognitive
neuroscience. Yet brain imaging can be a minefield, whichever
discipline you approach it from. If you are a psychologist, you
will have been taught how to do behavioural experiments, but may
know little neuroanatomy or neurophysiology. If you are a
neurologist or psychiatrist, then you may know the neuroanatomy and
neurophysiology, but not know how to carry out experiments on
mental phenomena. This is a practical guide to brain imaging,
showing how it can advance a true neuroscience of human cognition.
It is accessible to those starting out in imaging, whilst also
informative for those who have already acquired some expertise. At
the heart of the book are 6 main chapters, focusing on - the
signal, experimental methods, anatomy, functional specialisation,
functional systems, and other methods. For students and researchers
in psychology and neuroscience, this is the essential companion
when embarking on brain imaging studies.
