A brain atlas of the northern fulmar (Fulmarus glacialis) in stereotaxic coordinates.

The brain of a procellariiform bird, the Northern Fulmar (Fulmarus glacialis), is presented in the form of a stereotaxic atlas. The Northern Fulmar is especially interesting because both field and laboratory evidence support olfaction as one of its major sensory systems. The nasal cavity and olfactory bulb of most procellariiforms are among the largest of all avian orders; the central olfactory pathways may be more extensive as well. A brain atlas of the Northern Fulmar, a relatively accessible procellariiform species on which several studies have already been done, can provide reference for research both on neural mechanisms underlying olfaction and on comparative neuroanatomical data within Aves and between avian and nonavian groups.

Forebrain projections of the pigeon olfactory bulb.

The olfactory system of the pigeon (Columba livia) was examined. Our electrophysiological and experimental neuroanatomical (Fink-Heimer technique) data showed that axons from the olfactory bulb terminated in both sides of the forebrain. The cortex prepiriformis (olfactory cortex), the hyperstriatum ventrale and the lobus parolfactorius comprised the uncrossed terminal field. The crossed field included the paleostriatum primitivum and the caudal portion of the lobus parolfactorius, areas which were reached through the anterior commissure. In this report the relationships between areas that receive olfactory information and the possible roles that olfaction plays in the birds' behavior are discussed.

Decision to enter pulmonology: motives and implications.

A study was undertaken to determine at what time American-trained pulmonary disease specialists in two California counties made their subspecialty choices and the factors which influenced their decision. Responses to 281 questionnaires were received and analyzed from 171 fellows, faculty members, and practitioners (60.8 percent). Subspecialty decisions for pulmonology were usually made during residency, motivated by pulmonary rotations and exposure to stimulating faculty members. Although this subspecialty has recently developed into an established, growing field, the survey data confirmed that the amount of pulmonary interaction during medical school remains minimal.
