DISCRIMINATORY APPROACH TO AUDITORY STIMULI IN GUINEA FOWL (NUMIDA MELEAGRIS) AFTER HYPERSTRIATAL∕HIPPOCAMP- AL BRAIN DAMAGE

unilateral lesion of receptor or auditory pathways), repression of hypothetic-
al central specifications (e.g. by cycloheximide and related drugs) and control
of the individual’s experience of specific sensory stimuli. Such testing should
naturally include blind procedures for recording and analysis. Closer analogies
with mammalian studies of the limbic system must await more detailed ana-
tomical work. In the meantime the detailed analysis of behavioural compo-
nents such as movement, search, and posture-tension have been shown to be
useful tools for dissecting the possible role(s) of parts of the central nervous
system in attention-related processes.

ACKNOWLEDGEMENTS

I would like to thank Prof. Dr. H. Scheich for his support and interest, and
both him and Dr. V. Maier for their helpful discussions on an earlier draft of
this work. I am grateful to Fr. M. Hansel for the preparation of the diagrams,
to Fr. I. Roder for her histological preparations, and to the Deutsche For-
Schungsgemeinschaft for financial support.
