TI  - Afferent and efferent connections of the olfactory bulbs in the lizard Podarcis 
      hispanica.
PG  - 337-47
AB  - The connections of the olfactory bulbs of Podarcis hispanica were studied by 
      tract-tracing of injected horseradish peroxidase. Restricted injections into the 
      main olfactory bulb (MOB) resulted in bilateral terminallike labeling in the 
      medial part of the anterior olfactory nucleus (AON) and in the rostral septum, 
      lateral cortex, nucleus of the lateral olfactory tract, and ventrolateral 
      amygdaloid nucleus. Bilateral retrograde labeling was found in the rostral 
      lateral cortex and in the medial and dorsolateral AON. Ipsilaterally the dorsal 
      cortex, nucleus of the diagonal band, lateral preoptic area, and dorsolateral 
      amygdala showed labeled cell bodies. Retrogradely labeled cells were also found 
      in the midbrain raphe nucleus. Results from injections into the rostral lateral 
      cortex and lateral olfactory tract indicate that the mitral cells are the origin 
      of the centripetal projections of the MOB. Injections in the accessory olfactory 
      bulb (AOB) produced ipsilateral terminallike labeling of the ventral AON, bed 
      nucleus of the accessory olfactory tract, central and ventromedial amygdaloid 
      nuclei, medial part of the bed nucleus of the stria terminalis, and nucleus 
      sphericus. Retrograde labeling of neurons was observed ipsilaterally in the bed 
      nucleus of the accessory olfactory tract and stria terminalis, in the central 
      amygdaloid nucleus, dorsal cortex, and nucleus of the diagonal band. Bilateral 
      labeling of somata was found in the ventral AON, the nucleus sphericus (hilus), 
      and in the mesencephalic raphe nucleus and locus coeruleus. Injections into the 
      dorsal amygdala showed that the mitral neurons are the cells of origin of the AOB 
      centripetal projections. Reciprocal connections are present between AOB and MOB. 
      To our knowledge, this is the first study to address the afferent connections of 
      the olfactory bulbs in a reptile. On the basis of the available data, a 
      discussion is provided of the similarities and differences between the reptilian 
      and mammalian olfactory systems, as well as of the possible functional role of 
      the main olfactory connections in reptiles.
