Hemiparkinsonism associated with mesencephalic cavernoma: case report and review of literature

open access: yesBrazilian Neurosurgery, 2011
Parkinsonism is a movement disorder characterized by resting tremor, slow and decreased movements (hypokinesia and akinesia), rigidity, postural instability, problems with gait, and coordination.

Neuronal population of the mesencephalon, rhombencephalon and spinal cord in zebrafish (Danio rerio)

open access: yes, 2020
Anatomically central nervous system in zebra fish is represented by telencephalon, diencephalon, mesencephalon, mielencephalon and metencephalon. Histological study of neuronal population of mesencephalon, rombencephalon and spinal cord was made on 10 ...

Measurement of Anteroposterior diameters of normal brainstem by Magnetic Resonance Imaging

open access: yesJournal of Gandaki Medical College, 2019
Aim: The aim of this study is to assess the anteroposterior diameter of brainstem (midbrain, pons and medulla) of normal Nepalese people to establish normal ranges and to correlate the measurement with pa­tient’s age and gender. Method: The study is a

Possible Event-Related Potential Correlates of Voluntary Attention and Reflexive Attention in the Emei Music Frog

open access: yesBiology, 2022
Attention, referring to selective processing of task-related information, is central to cognition. It has been proposed that voluntary attention (driven by current goals or tasks and under top-down control) and reflexive attention (driven by stimulus ...

Bilateral Ageusia and Tongue Anesthesia Following Unilateral Brainstem Infarct: A Case Report with a Brief Review of the Literature

open access: yesCase Reports in Neurology, 2018
We present the case of a 63-year-old male patient who suffered bilateral ageusia following a unilateral left-sided mesencephalon infarct. To the best of our knowledge, this is the first description of a mesencephalon lesion leading to ageusia. We discuss

Temporal-spatial changes in Sonic Hedgehog expression and signaling reveal different potentials of ventral mesencephalic progenitors to populate distinct ventral midbrain nuclei [PDF]

open access: yes, 2011
Background: The ventral midbrain contains a diverse array of neurons, including dopaminergic neurons of the ventral tegmental area (VTA) and substantia nigra (SN) and neurons of the red nucleus (RN).

Auditory perception exhibits sexual dimorphism and left telencephalic dominance in Xenopus laevis

open access: yesBiology Open, 2018
Sex differences in both vocalization and auditory processing have been commonly found in vocal animals, although the underlying neural mechanisms associated with sexual dimorphism of auditory processing are not well understood.

Projection from dorsal column nuclei to dorsal mesencephalon

open access: yes, 1985
This study investigated the projection from the dorsal column nuclei (DCN) to the dorsal mesencephalon. Single-unit extracellular recordings were obtained from the DCN of alpha-chloralose anesthetized cats. Neurons were identified by standard antidromic

Central nervous system toxicity of manganese: Mechanism of manganese concentration in the ventral mesencephalon

open access: yes, 1996
In the lateral choroid plexus, Mn was sequestered from the blood against a concentration gradient. Intrathecal administration of Mn²⁺ showed that the choroid plexus does not remove Mn from the cerebrospinal fluid and that intrathecal Mn²⁺ rapidly caused ...

Toward Generating Subtype-Specific Mesencephalic Dopaminergic Neurons in vitro

open access: yesFrontiers in Cell and Developmental Biology, 2020
Mesencephalic dopaminergic (mDA) neurons derived from pluripotent stem cells (PSCs) have proven to be pivotal for disease modeling studies and as a source of transplantable tissue for regenerative therapies in Parkinson’s disease (PD).
