“…Subsequent studies (Brauth et al, 1978;Reiner, 1995, 1997;Reiner et al, 1998a), culminating with Jiao et al (2000), revealed the avian ALa to be a glutamatergic cell group that develops within the same prosencephalic region, is located in the same final adult position as the mammalian subthalamic nucleus, and is reciprocally connected with the pallidal part of the basal ganglia. In terms of its function, the neurotransmitters utilized by its inputs and outputs, its developmental profile, its position in the diencephalon, and its likely presence in reptiles, the ALa clearly appears homologous to the subthalamic nucleus of mammals (Reiner et al, 1998a;Jiao et al, 2000) . For this reason, the Forum concluded that the avian ALa should be renamed the subthalamic nucleus (STN; Table 1, Fig.…”

“…The Forum thus sought to rename the various parts of the subpallium in birds to reflect more accurately their homologues in mammals. In particular, we sought to identify and rename the striatal and pallidal subdivisions of the avian dorsal basal ganglia, which as a whole is largely involved in somatomotor functions Doupe and Kuhl, 1999;Jiao et al, 2000), as well as those of the ventral basal ganglia. As in mammals, the striatum and pallidum can be distinguished because their neuron types differ in morphology, neuropeptide content, connections, and electrophysiology (Reiner et al, 1984a(Reiner et al, , 1998aReiner and Anderson, 1990;Medina and Reiner, 1995;Farries and Perkel, 1000).…”

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 In particular, the outdated terminology implies that most of the avian telencephalon is a hypertrophied basal ganglia, when it is now clear that most of the avian telencephalon is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...

Sulfatase 1 is a secreted enzyme that modulates the sulfation state of heparan sulfate proteoglycans (HSPGs), which are potential key regulators of diverse developmental signals during embryonic patterning. In the present work, we have analyzed the Sulf1 gene expression pattern during chicken forebrain development. Our results indicate that, at early developmental stages, chicken Sulf1 is expressed in the alar and basal plate of the secondary prosencephalon (telencephalon and hypothalamus, respectively) as well as in the diencephalic basal and floor plates. Later in development, Sulf1 is expressed by a subset of nuclei derived from these regions. prosomere 1 (pretectum) p1MT p1 medial terminal nucleus p1PAG p1 periaqueductal gray p1PEW p1 pre-Edinger-Westphal nucleus p1Rt p1 reticular formation p1SNC p1 substantia nigra, compact part p1Tg p1 tegmentum area p1VTA p1 ventral tegmental area p2 prosomere 2 (thalamus) p2PAG p2 periaqueductal gray p2Tg p2 tegmentum area p2VTA p2 ventral tegmental area p3 prosomere 3 (prethalamus) p3Tg p3 tegmentum area p3VTA p3 ventral tegmental area pc posterior commissure Pe periventricular stratum PH posterior hypothalamic nucleus Pi pineal gland POA preoptic area PRot perirotundic area PrPT principal pretectal nucleus of the commissural pretectum PThB basal prethalamic nucleus Rh rhombencephalon rh1 rombomere 1 RM retromammillary nucleus RMC red nucleus, magnocellular part Rot rotundus nucleus RPC red nucleus, parvicellular part SAC stratum album centrale of the tectum SCh suprachiasmatic nucleus Se septum SGC stratum griseum centrale of the tectum SGFS stratum griseum et fibrosum superficiale of the tectum SHb subhabenular nucleus SLPG semilunar perigeniculate nucleus sm stria medullaris SMi superficial microcellular nucleus SP secondary prosencephalon SPa subparaventricular nucleus SPC superficial parvicellular nucleus of the thalamus SpL lateral spiriform nucleus SPT subpretectal nucleus SRot subrotundus nucleus of the thalamus STh subthalamic nucleus TC tuber cinereum area TEL telencephalom TGC tectal gray, central stratum vCaPa caudal paraventricular area, ventral part VisCo visual nidopallial nucleus, core region VisSh visual nidopallial nucleus, shell region VTgM ventral tegmental area of mammillary region VTgp1 ventral tegmental area of prosomere 1 VTgRM ventral tegmental area of retromammillary region xso supraoptic decussation ZLI intrathalamic limitans zone

“…The indirect pathway projects via globus pallidus externallike (GPe) neurons to the subthalamic nucleus which in turn projects to globus pallidus internal-like (GPi) neurons, to the substantia nigra pars reticulata (SNr) and to a pretectal nucleus called spiriformis lateralis (SpL). The projections to GPi and SNr increase inhibition on the motor thalamus and therefore have a net inhibitory effect on movements (Jiao et al, 2000). In the direct pathway, the striatum directly projects to GPi, SNr and SpL.…”

Striatal dopamine D1 receptors are involved in the dissociation of learning based on reward-magnitude

2013

Abstract-Here we investigate the contribution of striatal dopamine receptors (D1) to the influence of reward-magnitude on learning. Pigeons (Columba livia) were trained on a discrimination-task with two pairs of stimuli; correct discrimination resulted in a large reward in one pair of stimuli and in a small reward in the other pair. Acquisition of the discrimination-task was accompanied by intracranial injections to the medial striatum, either of a dopamine-antagonist (Sch23390) or of vehicle. In the control-condition the rate of learning was modulated by the magnitude of the reward; discrimination was learned faster if contingent rewards were large and learning was slower if contingent rewards were small. Following injections of D1 antagonist this effect vanished even though the ability to discriminate between the rewards was unaffected. Interestingly, the mean rate of learning was indistinguishable between the control and antagonist conditions. Consequently, it appears that not learning per se but the effect of reward-magnitude on learning is mediated through D1 receptors in the striatum. We argue that the injections of dopamine-antagonist cause a shift in strategy underlying learning. In the control-condition animals rely on positive feedback and thus learning is affected by the magnitude of the contingent reward; in the antagonist-condition, however, learning might rely on negative feedback and is thus insensitive to reward-magnitude.
