Presentazione a Gisella Gaspari e Matteo Pasetti, «Il Pci è un partito finito». Video-documentario sulla scomparsa della “piazza rossa”
Introduzione a un video-documentario realizzato dallo stesso autore (in collaborazione con Gisella Gaspari che ha curato il montaggio), utilizzando filmati d'epoca cine-amatoriali conservati negli archivi audiovisivi dell'Istituto per la storia e la memoria del '900 Parri E-R e dell'associazione culturale Home Movies. Attraverso immagini di manifestazioni a sfondo politico nelle piazze di Bologna, il video-documentario illustra una trasformazione delle forme di partecipazione collettiva alla vita pubblica, che negli anni Settanta ha visto un ridimensionamento del ruolo dei partiti di massa, e in particolare del Pci

Lingua e stile dell' 'io' nella declamazione latina. Appunti per una grammatica delle passioni
L’articolo prende in esame il linguaggio dell’interiorità nella declamazione latina, concentrandosi su alcuni stilemi frequenti nei testi declamatori per sottolineare lo stato d’animo del locutore: forme medio passive che evidenziano il patimento interiore; un tipo particolare di metonimia, qui definita ‘metonimia delle partes’, che rinvia a personaggi tipici (come il pater e il filius) per evocare i sentimenti che vengono loro tipicamente attribuiti; inoltre, la personificazione dell’animus e il ricorso all’indefinito nescioquis per esprimere le emozioni incoscienti e dunque incontrollabili dal soggetto. Questi tratti stilistici esercitano una notevole influenza sulla lingua letteraria di età imperial
Spinal and supraspinal stretch responses of postural muscles in early Parkinsonian patients.
Early Parkinson's disease (PD), in which the motor disorder is mostly unilateral, allows to investigate the presence of side-related pathophysiological changes in the responses to balance perturbations prior to any confounding effect of therapy. These patients offer the possibility of answering the question whether the initial abnormalities affect spinal circuits or supra-spinal sensori-motor loops. Toe-down rotation of a supporting platform evokes in standing subjects a double-burst medium-latency response (MLR) in the stretched tibialis anterior (TA) muscle. The former burst (MLR1) is fed by group II spindle fibres through a spinal circuit, the latter (MLR2) travels through supraspinal pathways. This perturbation was used to separately test both reflex pathways in both the unaffected and affected side. Ten patients with unilateral PD (7 of which de-novo) and 10 normal subjects (NS) were recruited. 1. Body sway and centre of feet pressure (CFP) were recorded during quiet standing; 2. Rotations of the supporting platform were administered with both legs on the platform during free stance (Control) and 3. While holding onto a stable rail (Holding); 4. Separate perturbations to either leg (Leg-on or Leg-off) were also delivered to avoid the effect of concurrent ipsi- and contralateral inputs on MLR. The EMG of TA and Sol muscles were recorded bilaterally. 1. Position and sway of CFP were similar in NS and PD. 2. Under Control condition, there were no differences in area of TA MLR1 and MLR2 of both limbs between NS and PD. 3. During Holding, both bursts were reduced in amplitude in both NS and PD, but less so for the MLR1 on the PD affected side. 4. During single-leg perturbation, both bursts were reduced in amplitude in both NS and PD, both ipsi- and contralateral to the perturbation; however, in PD, MLR2 was much less reduced in the unperturbed affected side Leg-off. The differences in the responses to stretch between NS and early PD are not accounted for by changes in postural attitude, or by different amplitudes of the Control responses. The asymmetrical reduction of the MLR1 by Holding in PD indicates mostly unilateral impairment of the descending pathways modulatory to spinal group II circuits. Single-leg perturbation unveils a larger excitability of the supraspinal loop mediating the MLR2 on the affected side. These changes are early markers of basal ganglia malfunctions, and are related to both their descending effect on the spinal cord and their ascending influence onto the cortex

Spinal and supraspinal stretch responses of postural muscles in early Parkinsonian patients
Early Parkinson's disease (PD), in which the motor disorder is mostly unilateral,
allows to investigate the presence of side-related pathophysiological changes in
the responses to balance perturbations prior to any confounding effect of
therapy. These patients offer the possibility of answering the question whether
the initial abnormalities affect spinal circuits or supra-spinal sensori-motor
loops. Toe-down rotation of a supporting platform evokes in standing subjects a
double-burst medium-latency response (MLR) in the stretched tibialis anterior
(TA) muscle. The former burst (MLR1) is fed by group II spindle fibres through a
spinal circuit, the latter (MLR2) travels through supraspinal pathways. This
perturbation was used to separately test both reflex pathways in both the
unaffected and affected side. Ten patients with unilateral PD (7 of which
de-novo) and 10 normal subjects (NS) were recruited. 1. Body sway and centre of
feet pressure (CFP) were recorded during quiet standing; 2. Rotations of the
supporting platform were administered with both legs on the platform during free
stance (Control) and 3. While holding onto a stable rail (Holding); 4. Separate
perturbations to either leg (Leg-on or Leg-off) were also delivered to avoid the
effect of concurrent ipsi- and contralateral inputs on MLR. The EMG of TA and Sol
muscles were recorded bilaterally. 1. Position and sway of CFP were similar in NS
and PD. 2. Under Control condition, there were no differences in area of TA MLR1
and MLR2 of both limbs between NS and PD. 3. During Holding, both bursts were
reduced in amplitude in both NS and PD, but less so for the MLR1 on the PD
affected side. 4. During single-leg perturbation, both bursts were reduced in
amplitude in both NS and PD, both ipsi- and contralateral to the perturbation;
however, in PD, MLR2 was much less reduced in the unperturbed affected side
Leg-off. The differences in the responses to stretch between NS and early PD are
not accounted for by changes in postural attitude, or by different amplitudes of
the Control responses. The asymmetrical reduction of the MLR1 by Holding in PD
indicates mostly unilateral impairment of the descending pathways modulatory to
spinal group II circuits. Single-leg perturbation unveils a larger excitability
of the supraspinal loop mediating the MLR2 on the affected side. These changes
are early markers of basal ganglia malfunctions, and are related to both their
descending effect on the spinal cord and their ascending influence onto the
cortex
