Recent trends in management strategies for two major maize borers: Ostrinia nubilalis and Sesamia nonagrioides
Stem borers (Lepidoptera) are common cereal pests. In many parts of the world, the species Ostrinia nubilalis and Sesamia nonagrioides stand out as important insect pests of economically important crops such as m...

Open AccessTop-down control of human motor thalamic neuronal activity during the auditory oddball task
The neurophysiology of selective attention in visual and auditory systems has been studied in animal models but not with single unit recordings in human. Here, we recorded neuronal activity in the ventral inte...

Are smartphones and machine learning enough to diagnose tremor?
Patients with essential tremor (ET), Parkinson’s disease (PD) and dystonic tremor (DT) can be difficult to classify and often share similar characteristics.

Sustainable Management of Insect-Resistant Crops
Sustainability is a goal-oriented process that advances with new knowledge. We discuss factors relevant to insect-resistant crops and sustainability: adoption patterns, insecticide use patterns and their influ...

Validation of Parametric Models in Microelectrode Recordings Acquired from Patients with Parkinson’s Disease
The Deep Brain Stimulation (DBS) has become one of the most common therapies applied to patients with Parkinson’s disease (PD). Microelectrode recordings (MER) are taken invasively to measure the electrical ac...

Open AccessThe potential global distribution of Chilo partellus, including consideration of irrigation and crop** patterns
Chilo partellus is a major crop pest in Asia and Africa, and has recently spread to the Mediterranean region. Knowledge of its potential distribution can inform biosecurity policies aimed...

The harlequin ladybird, Harmonia axyridis: global perspectives on invasion history and ecology
The harlequin ladybird, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), is native to Asia but has been intentionally introduced to many countries as a biological control agent of pest insects. In numerous...

Invasion biology of spotted wing Drosophila (Drosophila suzukii): a global perspective and future priorities
The Asian vinegar fly Drosophila suzukii (spotted wing Drosophila [SWD]) has emerged as a major invasive insect pest of small and stone fruits in both the Americas and Europe since the late 2000s. While research ...

Article
The chemical ecology of Harmonia axyridis
We review the chemical ecology of the ladybird beetle Harmonia axyridis from the perspective of its invasiveness and the deleterious effects it exerts in the regions it has colonised. We outline the nature and qu...

High-frequency microstimulation in human globus pallidus and substantia nigra
Deep brain stimulation of the basal ganglia and other brain regions has been used successfully to treat a variety of neurological disorders. However, the mechanisms by which it works, remain unclear. In a prev...

Inhibition of Neuronal Firing in the Human Substantia Nigra Pars Reticulata in Response to High-Frequency Microstimulation Aids Localization of the Subthalamic Nucleus
Deep brain stimulation (DBS) has been playing an increasing role in the treatment of various movement disorders with the most common being Parkinson’s disease (PD). Currently, the preferred target for treating...

Pedunculopontine nucleus microelectrode recordings in movement disorder patients
The pedunculopontine nucleus (PPN) lies within the brainstem reticular formation and is involved in the motor control of gait and posture. Interest has focused recently on the PPN as a target for implantation ...

Article
Firing rates of pallidal neurons are similar in Huntington’s and Parkinson’s disease patients
According to the now classical basal ganglia–thalamocortical circuitry model, the chorea of Huntington’s disease (HD) and the hypokinesia in Parkinson’s disease (PD) are explained by a decrease in the inhibito...

Eye movement-related responses of neurons in human subthalamic nucleus
Intraoperative microelectrode single unit recordings are routinely made in the subthalamic nucleus (STN) of awake and alert Parkinson’s disease (PD) patients during surgery for implantation of deep brain stimu...

Alterations in Globus Pallidus Internus Firing Patterns are Associated with Different Movement Disorders
Differences in neuronal firing rates of the globus pallidus internus (GPi) in hypokinetic and hyperkinetic movement disorders are thought to play an important role in mediating the contrasting motor symptoms. ...

Article
Stimulation-induced inhibition of neuronal firing in human subthalamic nucleus
The subthalamic nucleus (STN) is an important component of the basal ganglia (BG) and plays a major role in the pathogenesis of Parkinson’s disease (PD). Hyperactivity of STN as a consequence of the loss of do...

Chapter
Pathophysiology of the Internal Segment of the Globus Pallidus in Parkinson’s Disease
Although the internal segment of the globus pallidus (GPi) has been a neurosurgical target for some 50 years, only recently has a detailed analysis of the clinical effects of interventions in this region been ...

Chapter
Target Localization in Movement Disorders Surgery
The success of a stereotactic neurosurgical procedure is influenced by a number of factors. Proper patient selection is important in order to avoid treating patients unlikely to benefit from the procedure. Car...
