Perineuronal Nets and GABAergic cells in the Inferior Colliculus of Guinea Pigs

open access: yesFrontiers in Neuroanatomy, 2014
Perineuronal nets (PNs) are aggregates of extracellular matrix that have been associated with neuronal plasticity, critical periods, fast-spiking cells and protection from oxidative stress.

Vibrissal midbrain loops

open access: yesScholarpedia, 2011
The midbrain consists of the tectum and the tegmentum. The tectum comprises the inferior colliculus and superior colliculus. The tegmentum contains several areas including the periaqueductal gray, mesencephalic reticular formation (aka, deep mesencephalic nucleus), cuneiform nucleus (also commonly referred in rodents as deep mesencephalic nucleus ...

Sensory prediction errors in the human midbrain signal identity violations independent of perceptual distance

open access: yeseLife, 2019
The firing of dopaminergic midbrain neurons is thought to reflect prediction errors (PE) that depend on the difference between the value of expected and received rewards.

Mesencephalic basolateral domain specification is dependent on Sonic Hedgehog

open access: yesFrontiers in Neuroanatomy, 2015
In the study of central nervous system morphogenesis, the identification of new molecular markers allows us to identify domains along the antero-posterior and dorso-ventral axes.

Leptin and Insulin Signaling in Dopaminergic Neurons: Relationship between Energy Balance and Reward System

open access: yesFrontiers in Psychology, 2014
The central actions of leptin and insulin are essential for the regulation of energy and glucose homeostasis. In addition to the crucial effects on the hypothalamus, emerging evidence suggests that the leptin and insulin signaling can act on other brain ...

Neurosensory development of the four brainstem-projecting sensory systems and their integration in the telencephalon

open access: yesFrontiers in Neural Circuits, 2022
Somatosensory, taste, vestibular, and auditory information is first processed in the brainstem. From the brainstem, the respective information is relayed to specific regions within the cortex, where these inputs are further processed and integrated with ...

Palmitate and Stearate are Increased in the Plasma in a 6-OHDA Model of Parkinson’s Disease

open access: yesMetabolites, 2019
Introduction: Parkinson’s disease (PD) is the second most common neurodegenerative disorder, without any widely available curative therapy. Metabolomics is a powerful tool which can be used to identify unexpected pathway-related disease progression

Wnt1 Lineage Specific Deletion of Gpr161 Results in Embryonic Midbrain Malformation and Failure of Craniofacial Skeletal Development

open access: yesFrontiers in Genetics, 2021
Sonic hedgehog (Shh) signaling regulates multiple morphogenetic processes during embryonic neurogenesis and craniofacial skeletal development. Gpr161 is a known negative regulator of Shh signaling. Nullizygous Gpr161 mice are embryonic lethal, presenting
