Reflections on Consciousness in Intensive Care. [PDF]

open access: yesActa Paediatr
ABSTRACT Evaluating consciousness in intensive care is pivotal to relieving suffering with analgesic or sedative drugs and in prognosis and diagnoses. The usual clinical perspective is to equate consciousness with responsiveness, assuming functional motor responses and sympathetic activity of the patient. Clinical diagnoses of coma may be wrong in more

Functional Organization of the Spinal Locomotor Network Based on Analysis of Interneuronal Activity. [PDF]

open access: yesEur J Neurosci
In decerebrate cat, activity of spinal interneurons during locomotor movements evoked by stimulation of the mesencephalic locomotor region was recorded. We found that neurons were activated and inactivated preferably within one of the four phase ranges (I–IV).

Progressive clonic slowing predicts severity of respiratory dysfunction and prolonged postictal immobility in tonic-clonic seizures. [PDF]

open access: yesEpilepsia Open
Abstract Objective Progressive clonic slowing is a common electroclinical phenomenon observed during the clonic phase of bilateral tonic–clonic seizures (BTCS) and reflects an inhibitory phenomenon. We aimed to explore the relationship between progressive clonic slowing and biomarkers implicated in the pathophysiology of sudden unexpected death in ...

Multimodal Breathing Control: Pontomedullary Mechanisms and Current Perspectives. [PDF]

open access: yesBioessays
Breathing is typically automatic, ensuring homeostasis, but it is also shaped by emotion, behavior, and volition. This review synthesizes our current understanding of the flexible neural mechanisms that enable multimodal control of breathing, emphasizing the role of pontomedullary circuits.

Is there an integrative center in the vertebrate brain-stem? A robotic evaluation of a model of the reticular formation viewed as an action selection device [PDF]

open access: yes, 2005
Neurobehavioral data from intact, decerebrate, and neonatal rats, suggests that the reticular formation provides a brainstem substrate for action selection in the vertebrate central nervous system.

Push-Pull Control of Motor Output [PDF]

open access: yes, 2012
Inhibition usually decreases input–output excitability of neurons. If, however, inhibition is coupled to excitation in a push–pull fashion, where inhibition decreases as excitation increases, neuron excitability can be increased. Although the presence of

Pre- and Post-alpha Motoneuronal Control of the Soleus H-reflex during Sinusoidal Hip Movements in Human Spinal Cord Injury [PDF]

open access: yes, 2006
The aim of this study was to establish the contribution of hip-mediated sensory feedback to spinal interneuronal circuits during dynamic conditions in people with incomplete spinal cord injury (SCI).

Producing alternating gait on uncoupled feline hindlimbs: Muscular unloading rule on a biomimetic robot [PDF]

open access: yes, 2014
Studies on decerebrate walking cats have shown that phase transition is strongly related to muscular sensory signals at limbs. To further investigate the role of such signals terminating the stance phase, we developed a biomimetic feline platform ...

From Parallel Sequence Representations to Calligraphic Control: A Conspiracy of Neural Circuits [PDF]

open access: yes, 2004
Calligraphic writing presents a rich set of challenges to the human movement control system. These challenges include: initial learning, and recall from memory, of prescribed stroke sequences; critical timing of stroke onsets and durations; fine control

Neuronal mechanisms of feedback postural control [PDF]

open access: yes, 2016
Different species maintain a basic body posture due to the activity of the postural control system. An efficient control of the body orientation, as well as the body configuration, is important for standing and during locomotion.
