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 ...

Essential role for PDGF signaling in ophthalmic trigeminal placode induction [PDF]

open access: yes, 2008
Much of the peripheral nervous system of the head is derived from ectodermal thickenings, called placodes, that delaminate or invaginate to form cranial ganglia and sense organs.

Snail2 directly represses cadherin6B during epithelial-to-mesenchymal transitions of the neural crest [PDF]

open access: yes, 2007
The neural crest, a transient population of migratory cells, forms the craniofacial skeleton and peripheral nervous system, among other derivatives in vertebrate embryos. The transcriptional repressor Snail2 is thought to be crucial for the epithelial-to-

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

The Search for Invertebrate Consciousness [PDF]

open access: yes, 2020
There is no agreement on whether any invertebrates are conscious and no agreement on a methodology that could settle the issue. How can the debate move forward?
