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

Brazilian 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.

MRI diffusion and perfusion alterations in the mesencephalon and pons as markers of disease and symptom reversibility in idiopathic normal pressure hydrocephalus.

PLoS ONE, 2020
IntroductionCore symptomatology in idiopathic normal pressure hydrocephalus (iNPH) points at dysfunction in the mesencephalon and pons indicating pathological changes in these regions, but only a few studies have addressed the issue.

Peripheral Inflammation Enhances Microglia Response and Nigral Dopaminergic Cell Death in an in vivo MPTP Model of Parkinson’s Disease [PDF]

, 2018
The impact of systemic inflammation in nigral dopaminergic cell loss remains unclear. Here, we have investigated the role of peripheral inflammation induced by systemic lipopolysaccharide (LPS) administration in the MPTP-based model of Parkinson’s ...

Halcyornis toliapicus (aves: Lower Eocene, England) indicates advanced neuromorphology in Mesozoic Neornithes [PDF]

, 2011
Our recent X-ray micro computer-tomographic (μCT) investigations of Prophaethon shrubsolei and Odontopteryx toliapica from the Lower Eocene London Clay Formation of England revealed the avian brain to have been essentially modern in form by 55 Ma, but ...

Measurement of Anteroposterior diameters of normal brainstem by Magnetic Resonance Imaging

Journal 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

Isthmus organizer and regionalization of the mesencephalon and metencephalon

The International Journal of Developmental Biology, 2005
The brain vesicles that are formed at an early stage of neural development are the fundamentals of the brain plan. Heterotopic transplantation revealed that the diencephalon could change its fate when juxtaposed to the isthmus (mes-metencephalic boundary), which indicated that the isthmus functions as an organizer for the mesencephalon and ...

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

Case 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

Visual and Electrosensory Circuits of the Diencephalon in Mormyrids [PDF]

, 1990
Mormyrids are one of two groups of teleost fishes known to have evolved electroreception, and the concomitant neuroanatomical changes have confounded the interpretation of many of their brain areas in a comparative context, e.g., the diencephalon, where ...

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

Biology 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.

Toward Generating Subtype-Specific Mesencephalic Dopaminergic Neurons in vitro

Frontiers 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).
