The "functional" in the title of this book not only reflects my personal bias about neuroanatomy in brain research, it is also the gist of many chapters which describe sophisticated ways to resolve structures and interpret them as dynamic entities. Examples are: the visualization of functionally identified brain areas or neurons by activity staining or intracellular dye-iontophoresis; the resolution of synaptic connections between physiologically identified nerve cells; and the biochemical identification of specific neurons (their peptides and transmitters) by histo- and immunocytochemistry. I personally view the nervous system as an organ whose parts, continuously exchanging messages, arrive at their decisions by the cooperative phenome non of consensus and debate. This view is, admittedly, based on my own ex perience of looking at myriads of nerve cells and their connections rather than studying animal behaviour or theorizing. Numerous structural studies have demonstrated that interneurons in the brain must receive hundreds of thousands of synapses. Many neurons receive inputs from several different sensory areas: each input conveys a message about the external world and possibly also about past events which are stored within the central nervous system. Whether an interneuron responds to a certain combination of inputs may be, literally, a matter of debate whose outcome is decided at the post synaptic membrane. A nerve cell responding to an overriding command is possibly a rare event.

This booklet is a commendable self-help learning and institutional pedagogic tool. It is part of a larger book whose granular interface starting with the Mankon Language sound and writing systems through grammar and vocabulary studies to historical discourse, facilitates the learning of the language. The language learning approach is situational-based with re-enforcement dialogues and passages reflecting everyday life. The pictorial illustrations are an adjuvant for word and scenic "imaging" for easier meaning decoding. Of course, each unit culminates in a test exercise.

This book is a descriptive and documentary analysis of the Mankon I-language and E-language mirrored through aspects of history, geography, flora and fauna. These aspects manifest in the taxonomic nomenclatures attributed to referents in society. Because these referents were hitherto transmitted orally from generation to generation, the author has painstakingly analysed and documented aspects of Mankon culture for posterity. The work focuses in particular on Mankon proverbs for insights into the structure and function of the language. As a vehicle of communication, language plays a primordial role in encoding and decoding 'metalinguistic' data. Through thorough scientific linguistic universals and principals, Chi Che has proposed orthography for Mankon pedagogy that is simple, tenable and practicable. This book is the answer to the international clarion call for societies to analyse and document their endangered indigenous cultures. Schools, linguists, sociolinguists, anthropologists, historians and others will find this book especially useful.
