“…The oval nucleus of the HV is a distinct region recognized in parrots that is part of their telencephalic vocal control circuit (Striedter, 1994;Durand et al, 1997). A similar region has also been observed in songbirds and hummingbirds (Jarvis et al, 1998.…”

“…The Forum recognized that the change in the name of the LPO to the medial striatum does affect the name for the part of the budgerigar medial striatum involved in vocal control (Ball, 1994;Striedter, 1994;Durand et al, 1997), because LPO was part of the name for this structure. The Forum recommended that this region henceforth be called the magnocellular nucleus of the medial striatum.…”

“…In guinea fowl, chicken, and pigeon, L1 is dorsomedial and L3 is ventrolateral to L2 (Bonke et al, 1979a;Heil and Scheich, 1985;Mü ller and Scheich, 1985;Wild et al, 1993). In songbirds, however, L1 is rostrodorsal, and L3 is caudoventral to L2 (Mü ller and Scheich, 1985;Fortune and Margoliash, 1992; Abbreviation retained, but capitalize C for consistency Brauth and McHale, 1988Striedter, 1994Durand et al, 1997 Summary of the nomenclature recommendations of the Forum for the neostriatum and the major subdivisions within it, proceeding largely in a rostral to caudal order (with specialized structures involved in vocal control or audition listed last).

“…Specialized nuclei involved in vocalization or audition have been identified within the archistriatum intermedium of songbirds, parrots, hummingbirds, and pigeons Wild et al, 1993). These include the robust nucleus of the archistriatum (RA) of male songbirds and females of some songbird species (Figs 7D, 9D;Nottebohm et al, 1976;Bottjer et al, 1989;Wild, 1993;Margoliash, 1997;Nordeen, 1997), the central nucleus of the anterior archistriatum in parrots (Aac; Paton et al, 1981;Striedter, 1994;Durand et al, 1997), the vocal nucleus of the archistriatum (VA) in hummingbirds , and the ventromedial and dorsomedial nuclei of the intermediate archistriatum (Aivm and Aidm) in pigeons . With the renaming of the archistriatum, the name for each of these is altered by replacing archistriatum with arcopallium, and the abbreviation remains the same, except for full capitalization ( Table 5).…”

The standard nomenclature that has been used for many telencephalic and related brainstem structures in birds is based on flawed assumptions of homology to mammals. In particular, the outdated terminology implies that most of the avian telencephalon is a hypertrophied basal ganglia, when it is now clear that most of the avian telencephalon is neurochemically, hodologically, and functionally comparable to the mammalian neocortex, claustrum, and pallial amygdala (all of which derive from the pallial sector of the developing telencephalon). Recognizing that this promotes misunderstanding of the functional organization of avian brains and their evolutionary relationship to mammalian brains, avian brain specialists began discussions to rectify this problem, culminating in the Avian Brain Nomenclature Forum held at Duke University in July 2002, which approved a new terminology for avian telencephalon and some allied brainstem cell groups. Details of this new terminology are presented here, as is a rationale for each name change and evidence for any homologies implied by the new names.Revisions for the brainstem focused on vocal control, catecholaminergic, cholinergic, and basal ganglia-related nuclei. For example, the Forum recognized that the hypoglossal nucleus had been incorrectly identified as the nucleus intermedius in the Karten and Hodos (1967) pigeon brain atlas, and what was identified as the hypoglossal nucleus in that atlas should instead be called the supraspinal nucleus. The locus ceruleus of this and other avian atlases was noted to consist of a caudal noradrenergic part homologous to the mammalian locus coeruleus and a rostral region corresponding to the mammalian A8 dopaminergic cell group. The midbrain dopaminergic cell group in birds known as the nucleus tegmenti pedunculopontinus pars compacta was recognized as homologous to the mammalian substantia nigra pars compacta and was renamed accordingly; a group of ␥-aminobutyric acid (GABA)ergic neurons at the lateral edge of this region was identified as homologous to the mammalian substantia nigra pars reticulata and was also renamed accordingly. A field of cholinergic neurons in the rostral avian hindbrain was named the nucleus pedunculopontinus tegmenti, whereas the anterior nucleus of the ansa lenticularis in the avian diencephalon was renamed the subthalamic nucleus, both for their evident mammalian homologues.For the basal (i.e., subpallial) telencephalon, the actual parts of the basal ganglia were given names reflecting their now evident homologues. For example, the lobus parolfactorius and paleostriatum augmentatum were acknowledged to make up the dorsal subdivision of the striatal part of the basal ganglia and were renamed as the medial and lateral striatum. The paleostriatum primitivum was recognized as homologous to the mammalian globus pallidus and renamed as such. Additionally, the rostroventral part of what was called the lobus parolfactorius was acknowledged as comparable to the mammalian nucleus accumbens, which, together with the...

Recordings of extracellular unit activity in the ventrolateral medulla and of electromyographic activity in either the M. scalenus, a principal inspiratory muscle, or the abdominal expiratory muscles, were used to identify inspiratory related (IR) neurons. IR neurons extended from levels caudal to the obex through the caudal level of the descending vestibular nucleus. This distribution was found to correspond to that of a subset of cells retrogradely labeled from injections of neuronal tracers into the upper thoracic spinal cord, where motoneurons innervating the M. scalenus were located by retrograde transport. Injections of biotinylated dextran amine at the recording sites resulted in projections to the spinal cord and brainstem. Bulbospinal axons traveled in the lateral funiculus, predominantly contralaterally, and terminated in relation to the dendrites and cell bodies of motoneurons innervating the M. scalenus. Brainstem nuclei receiving projections from injections at IR loci included the retroambigualis, tracheosyringeal motor nucleus, ventrolateral nucleus of the rostral medulla, infraolivaris superior, ventrolateral parabrachial nucleus, and the dorsomedial nucleus of the intercollicular complex. In the finches, there were also bilateral projections to nucleus uvaeformis of the posterior thalamus. The spinal and brainstem projections are similar to those found in pigeon (Reinke and Wild, [1997] J. Comp. Neurol. 379:347-362), and probably mediate the intricate coordination of the vocal (syringeal) and respiratory systems for the control of vocalization. The distribution of IR neurons in birds is similar to that of the rostral ventral respiratory group (rVRG) in mammals.

Methionine enkephalin immunoreactivity in the brain of the budgerigar (Melopsittacus undulatus): Similarities and differences with respect to oscine songbirds

The brain of the budgerigar (Melopsittacus undulatus), a small parrot that acquires new vocalizations throughout life, was examined for immunoreactivity to the opioid peptide methionine enkephalin (mENK). mENK is a highly prominent feature of the chemical architecture of the forebrain vocal system of oscine songbirds. Forebrain vocal control nuclei are believed to have evolved independently in parrots and songbirds (Streidter [1994] J. Comp. Neurol. 343:35-56); however, recent studies have found similarities in the neural organization of vocal control pathways in budgerigars and songbirds (Durand et al. [1997] J. Comp. Neurol. 377:179-206). Among the similarities are the existence of recursive pathways interconnecting vocal control neurons in the archistriatum, basal ganglia (i.e., lobus parolfactorius), and dorsal thalamus. In the present study, we found that all vocal control nuclei within the budgerigar forebrain exhibit prominent mENK-like immunoreactivity (ELI) in fibers and somata. We also found striking similarities between the morphology of ELI elements in budgerigar vocal control nuclei and that described previously in songbird vocal nuclei. Despite these similarities, the budgerigar dorsal striatopallidum (lobus parolfactorius, paleostriatum augmentatum, and paleostriatum primitivum) and somatomotor (anterior) archistriatum exhibit unique patterns of ELI. The dorsal striatopallidum contained far less ELI, whereas the archistriatum contained far more than would be expected on the basis of previous studies of opioid peptides in other avian species, including pigeons, chickens, and songbirds. These differences may reflect neural specializations unique to the budgerigar that contribute to the extraordinary flexibility of the vocal motor system of this species to acquire socially significant stimuli throughout life.
